Thumbs up for Sat Nav
My old PDA has been retired to my drawer. The Sat Nav on the XDA works great. Most impressive is the GPS mouse I got. That thing is awesome compared to my old one. Used to have to make sure it was right under the windscreen for it to get a signal. This new one will even work in my bag on the passenger seat... it even worked the other day when my phone was telling me bluetooth was switched off :|.
Tom Tom does wot Tom Tom does... I was more concerned about performance and trying to juggle sat nav and phone but its been quite a smooth experience. Turn Sat Nav on off you go.. call comes in.. sat nav screen flashes up with who is calling.. answer call using one of the hard or soft buttons or button on bluetooth headset... Sat Nav screen still remains on at the front and it mutes the Sat Nav sound whilst you are in the call.. once your finished with the call sound is automatically unmutted.. cant ask for much more. To make a call either use the voice command software or press the hard call button to switch to the phone screen.
Having the PDA on external power whilst being used for Sat Nav is essential as combination of screen being always on and bluetooth eats battery.
