Garmin C510 hack to add text-to-speech function

Mar 28, 2007 garmin, google, gps navigation, hacks

If you own one of these Garmin C510′s (or C530‘s) you must have realized that it doesn’t speak street names (a.k.a “text-to-speech”) – but this is a standard feature on the C550 and C580. Well, this advanced Garmin user (Phillip Hornby) has posted full instructions on how to hack into the C510 – download the sound files from Garmin after deleting some unnecessary files, and do a permanent install so your changes stick.

Here is a quote for some encouragement:

So to continue our example, connect the C510 in its conventional Mass-Storage-Mode and copy the \Garmin\Voice\English_British_Emily.VPM file to \Garmin\Voice\000.NEW. Also copy \Garmin\Voice\English_British.sum to \Garmin\Voice\English_British_Emily.sum.
You need to end up with the following new files in the \Garmin\Voice directory :-
English_British_Emily.vpm This is your new TTS voice file.
000.NEW (they’re zeroes)This is a copy of the file listed above (eg English_Britsh Emily.vpm)
English_British_Emily.sum This is a copy of one of your original .SUM files

Go ahead and give it a try… Come on… via

I am looking to add TTS to my ATT Tilt. Would I be able to take this TTS file you are referring to and load it on my phone?

I would like to try it if you would be willing to pass on the .vpm file foe review. Let me know.

Thanks
