MG-950D
Dec 21, 2007 CES 2008, bluetooth, fitness, gps navigation

MainNav is getting ready to introduce the new MG-950D at CES 2008. MG-950D is a bluetooth GPS data logger that has a lot functions that make it useful for hiking, biking, driving, and maybe even running.
It is similar to Garmin Edge 305 in terms of form factor but MG-950D also acts as a bluetooth GPS receiver, meaning you can share the GPS data with other devices. It uses a SiRF Star III GPS receiver and can store up to 120,000 waypoints. It can calculate speed and altitude while you workout and store that info so later on you can transfer it to your PC via the USB interface and view on Google Earth.
We have no information on pricing or where/when it will be available but we’ll investigate at CES 2008 for you.

Yeah, this blog was from a while ago, so I just want to add that Semsons & Co. Inc. is selling this item. They are offering free shipping and an additional 10% off (coupon code “MG950D”). It’s a limited time promotion (at least that’s what Semsons’ blog said). I got mine already and it’s pretty cool! I’ll probably get one for my brother as well since he’s such an athletic nut.
July 7th, 2008 at 12:18 pm
I’ve got one from Semsons too but the unit was having some issues. It would freeze or stop responding to buttons. I could not even turn the unit off or touch the >| button on the middle of the unit to proceed to next page.
I found out from the manufacturer that there is a newer firmware, version 1.16.
Eglantine, are you having the same issue with yours?

Hello Mike :
this is Cecily from Mainnav. This problem is because battery . You could take out battery and try it again. If still can’t work , you may feel free to contact me, I will try my best to solve your problem.

By the way, MG-950d now has new software .For update , please check mainnav website —www.mainnav.com check out “support”
July 31st, 2008 at 8:11 am
I thought the MG-950d was a GPS but reading the manual it appears it is just a data logger – the manual states the 950d can be connected to a GPS in order to log NEMA data. Strange – it evidently has GPS capabilities to perform its advertised functions.
The initial CES screen shots had lat/long displayed and I was hoping to use the device in the field to capture and occasional point via the screen. The manual screen shots no longer show lat/long. I guess the MG-950d won’t work for me.
August 4th, 2008 at 4:34 am
Hello Bob:
MG-950d is GPS cycle computer plus data logger. The design is especially for biking( of course driving ). Now the monitor does not have Lat/Log is because for most biker and driver , they do not need these.
This is MG-950d testing feedback , you may check.

The GPS Data on my 950d is sometimes a bid of the way and becomes very random when standing still for a while. Is this normal?
Also noticed Problems withe the battery but could fix it after putting a little piece of paper under it. Otherwise the device will turn after riding bike some meters.
August 7th, 2008 at 4:15 am
Dear Biker :
It’s normal for bid away while you stand for a while , no worries.
For battery , we notice this problem.Could you let me know your shipping address, I will send you sticker for back cover .

August 7th, 2008 at 4:51 pm
Just got mine today…took it for a ride. I bought it for it’s bike computer capabilities not for logging.
Love it. Better than dealing with those spoke magnets.
How can you tell what firmware you have?
August 7th, 2008 at 11:24 pm
Dear Tony :
New firmware is only for data logger part, if you only use on biker computer capabilities , you don’t have to update it. If you need update new firmware, you could send back to us (only unit ). We could do this service for you.
If possible, let us know your comment and testing feedback. We are glad to hear it.

Hello!
It seems that the picture of the display above is not the
same as the real display. I wanted to use the mg-950d
while flying with my paraglider (logging the flight-details)
AND to know my exact position after I have landed.
Is it still possible to see latitude and longitude on the
display? The manual does only show pictures with two
main rows on the display (speed/elevation, speed/time,
speed/total mileage, speed/trip time, speed/moved
distance, speed/average speed, speed/maximum speed
and ‘clear the data’)!?
Thank you!
Bernd Leutenecker
August 10th, 2008 at 8:49 pm
Dear Bernd :
For MG-950d, it’s differnt display like above. The monitor did not show Latitude and logitude . It features with cycle computer for biking.
MG-950d feature with Touch pad , it could easy to scan next page by touching .
For Mainnav Spot GPS watch MW-705D , it could records your POI and show the Latitude and Logitude. For sport watch , it’s more functionality .

I using MG-950d GPS cycle computer for my biking. Pretty well !! The screen is big enough to check out all figures . It
Data logger is new for biker , records all your tracks while you biking for new place . But it did not have POI function. Sometimes I would like to record my favorite spot /position on my bike trip .
Brief , I like it , not bad.
August 11th, 2008 at 5:25 pm
Nice BT gps/datalogger. I get it 4 days ago and I’m very happy with it.
Agree with Cynthia, a poi fuction would be great. And also any soft for dowloading the track to a WM PPC or symbian smartphone (the symbian is the one I would prefer)
August 11th, 2008 at 9:07 pm
I have one too, the photo mapping and data logger are really interested me since I used to be use cycle computer for my biking. MG-950d feature with GPS, so I bought one to try. So far so good.
What’s “POI” mean ?
August 12th, 2008 at 12:06 am
“POI” = Point Of Interest. That means, you could record a specific point (like a manantial, a police radar or what ever you want …) It’s usefull to do that just pushing a button, not having to record it in you smart phone or PPC.
August 12th, 2008 at 12:31 am
Oh , I see . Thank you very much for your answering , not bad function !!
August 12th, 2008 at 12:32 am
I got it. Thank you very much for your answering , not bad function !!
August 20th, 2008 at 12:38 am
Mainnav new software is update on website. The new software show more detail figures of biking data.
August 20th, 2008 at 4:22 am
Hello I recently bought it and have a problem – when connect to power supply or usb (to computer) gps is frezzing and not sending any data via usb or bluetooth. biker functions work I can change via>>| clock is workign, but gps freeze no km/h it stuck in the moment when connecting. I’m not able to use with trekbuudy on my mobile when connected to power supply. Do you have similar problems? Any idees?
August 21st, 2008 at 12:27 am
Dear Deluge :
May I know where did you buy the unit ? Thanks
August 21st, 2008 at 12:38 am
May I know did you use Mainnav car charger or yours ? When charging , GPS frezzing is normal , this is original design . For car , if you use Mainnav car charger , it would be ok for sending data.
if possible , you could send your car charger to sales@mainnav.com check it.
August 21st, 2008 at 2:42 am
when GPS is charging from car charger it is not freezing and working ok. So it is normal, thats I wanted to know. But it’s a shame that Im not able to use USB when playing with GPS. ;).
August 21st, 2008 at 8:59 pm
When using USB charging , the GPS is freezing , this is normal — Mainnav original design , it’s not bug.
August 27th, 2008 at 2:25 pm
Hi all
i got my MG 950d today, yeah, but it freezed on the first bike tour. :[
Some posts above Cecily said, try to open it and take out battery.
That worked but I hope that doesn’t happen again.
Is there a possibility to update the 950d firmware?
I will post in a week or so again.
No Problems at charging from power supply or USB. By Car charger not testet.
September 1st, 2008 at 2:34 am
Dear Mark :
Could you check your inside battery cover has sticker on it or not ? this is probable battery connect not so tight, Mainnav has improve this situation . For Firmware update, it needs send back to Mainnav for upgrade.
Cecily
September 3rd, 2008 at 6:41 am
No sticker on the battery cover. Just behind the battery a serial number. Last biketour the logger wasn’t charged, so no second test report :(
Btw.: I have the new MG-950D, should I post there? ( http://www.navigadget.com/index.php/2008/08/22/the-new-mg-950d-from-mainnav )
September 10th, 2008 at 9:10 pm
Dear Mark :
If you need the sticker, please offer me your shipping address, I could send you soon. You may pose it , no problem at all. Thanks.
September 20th, 2008 at 11:38 am
[...] MG-950d has changed its design since we last talked about it. Compared to older MG-950D current design is more sturdy and best of it all it is [...]
October 21st, 2008 at 11:45 pm
I bought last version of mg950d an have some problems with bt communication. With SE P1i datalogger periodically switch off bt and after ~1min resume communication with phone. I’ve also got old nemerix based gps receiver that working perfectly with p1i.
November 5th, 2008 at 4:28 pm
Note: my MG950d i bought from Ebay, would not power up, it has a foam pad holding down the battery, and it was on charge for the full time.
I bought a new battery [nokia BL-5c] from ebay and now the MG950d works with no problems. it would seem the standard battery is a problem.
November 10th, 2008 at 12:32 pm
I get my MG950D last week. I have try to connect it via BT with my MDA COMPACT 1. It will be found by the Navi Software and 2 sec. later the MG950D is freezed. No funktion left. I have to remove the battery to shut down.
I tryed it with 2 other HTC-Phones – the same behavior.
What shell we do ?
November 12th, 2008 at 12:07 am
HI Glenn:
For battery , Mainnav is sorry about this issue. If you would like to have another one battery , we could send you free one. Just feel free to let us know your demand.

I have the GPS above and it is brand new but does not show any bars by satelight icon, the device does not find a satelight no matter how long I leave it on. What should I do?
November 29th, 2008 at 4:35 am
On November 15, 2008 I bought a new MG-950d GPS LOGGER BLUETOOTH USB RECEIVER TACHOMETER from http://www.hardware-tech.de, (EBAY seller). It worked normally
until yesterday. The problem is that the unit cannot be turned on, even with the full battery.
The unit first froze and stopped responding to buttons. I could not even turn the unit off or touch the >| button on the middle of the unit to proceed to next page. I took out the battery and tried it again, but still could not turn the unit on.
Di I need a new battery or do I have to upgrade the firmware?
The serial number of the unit is 950d-02643.

Hi, I have strange problem with my MG-950d I’ve bought 3 weeks ago. When I try to download the recorded track (via BT) using the Mainnav software it displays the download window with two progress bars. The one at the top (with an arrow icon on the left) goes from 0% to 100%, but then it freezes – the progress bar at the bottom (the one with floppy disk icon) stays on 0% forever. I’ve tried it many times – same result.
MG-950d communicates with other devices (mobile, PC) without problems – it sends the NMEA data. Just the datlogger part doesn’t allow to download the recorded data.
Do you have any ideas what could be wrong and how to fix that? The serial # of the unit is 950d03872.
January 6th, 2009 at 12:56 pm
New version of the Mainnav software (2.0.1.5) fixed the problem.

Hello, why not put a firmware update for mg-950d? It would be very useful for the owners and less shipping costs for all.
Thank you
June 18th, 2009 at 10:36 am
I just recently bought the Mainnav MG-950dm.
Today after switching it on I noticed after a while that the tracker didn’t display speed, time etc. The battery was fully charged. I later realized that the tracker freezes ones it picks up a GPS signal which causes that e.g. the control button doesn’t react or that it is no longer possible to turn the tracker off. The only way to switch it off was by removing the battery.
After reseting the tracker I was able to connect the device and delete all the tracks using the Mainnav GPS Appplication. However this does not change the situation. Once you take it outside it will freeze after around 30 sec.
I searched if there is a firmware update available before I RMA the device but I’ve found nothing. Can someone help me with this problem or do I need to RMA the Tracker ? Is there a place where I could possibly download a new firmware ? Have you heard of this problem before ?
June 19th, 2009 at 2:24 am
I just talked with Mainnav in Taipei. From what I understand there was a change in the US GPS satellite communication that causes this freeze.
A collegue of mine noticed the same problem.
So this may affect all MG-950dm.
They told me that they will release new firmware next week.
Let’s see ! I’ll add another post as soon that I know more.
June 19th, 2009 at 6:39 am
Here’s what I received from Cecily at Mainnav (Thanks !!!!)
The MG-950dm isn’t working at the moment because the USA is maintaining satellite, they update new Almanac Data. The chipset supplier has changed the Firmware for client update. The new firmware will be available next week. Once it available, I will send you for update, please no worries.
It’s nothing about the device .
Temporarily, For MTK and Mstar chip set, they all have these problem. Only
SiRF and U-blox are working.
July 1st, 2009 at 5:15 am
I’ve got my new MG-950dm, it cannot connect to GPS satellites indoor, the GPS signal just disappears. Is there any work-around?
Peter, how about the new firmware?
July 7th, 2009 at 2:33 am
Hi LanDo
I have not heard back from Mainnav regarding the new firmware.
Mine is able to pick up the signal again (after about 1-2 weeks not working).
No idea why.
But this does not seem to be your problem. You say that yours is not able
to pick up the signal indoor. This is quite normal!! It all depends how the
house is built. If yours works outside then everything is ok.
Changing the firmware won’t make a difference.
July 16th, 2009 at 12:30 am
New firmware for MG-950dm is now available at Mainnav.com
October 11th, 2009 at 5:49 am
Hallo,
I bougth a MG-950dm just a week ago. I installed the software from the CD. But I cannot tranfer data to Laptop with USB interface. There is no respond, upload dosnot start. What is wrong?
With regards
Helmut
