Well, the Mobile Geo, GW Sense navigation and Sendero GPS products are all based on the same SDK (Software Developers Kit). The Mobile Geo product will run on Windows Mobile Smartphones, Windows Mobile Pocket PC and Windows Mobile PDAs; GW Sense Navigation will run on the Braille Sense, Voice Sense and Braille Sense Plus; the Sendero GPS will run on the Braille/VoiceNote mPowers and PK. Basically, this means that the meat of the products are the same but there are different names with slightely different features and behaviors for different products.
