It is impossible to traslate anything from this site, but they have pics of a what seems to be GPS navigation capable phone. Also after some research I figured out that the phone is actually manufactured by Sanyo, and it doesn’t actually integrate a GPS receiver chip. It uses FOMA which is a standard service only in Japan, offered by DoCoMo.

WCDMA

W-CDMA (Wideband Code Division Multiple Access) is a type of 3G cellular network. W-CDMA is the technology behind the 3G UMTS standard and is allied with the 2G GSM standard.

More technically, W-CDMA is a wideband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the general multiplexing scheme, not to be confused with CDMA the standard).

W-CDMA was developed by NTT DoCoMo as the air interface for their 3G network FOMA. Later NTT DoCoMo submitted the specification to the International Telecommunication Union (ITU) as a candidate for the international 3G standard known as IMT-2000. The ITU eventually accepted W-CDMA as part of the IMT-2000 family of 3G standards. Later, W-CDMA was selected as the air interface for UMTS, the 3G successor to GSM.

FOMA

FOMA, officially short for Freedom of Mobile Multimedia Access, is the brand name for the 3G services being offered by Japanese mobile phone operator NTT DoCoMo.

FOMA was the world’s first W-CDMA 3G service when launched in 2001. FOMA is compatible with standard UMTS, both via the radio link as well as via USIM card exchange, and hence provides several alternative options for global roaming: either with or without change of handset. Since mobile services in Japan are generally more advanced than in most other countries, e.g. FeliCa-i-Mode Wallet Phones, i-Mode mobile data services etc, to obtain full benefit of FOMA services local Japanese handsets are used.
