Re: Updating Navigation
In my other car I have mounted a Google Nexus7, running a code called Car Home Ultra (and a few other utility codes). I draw power from the car's 12V and pipe the audio through the stock radio's aux port.
With my Note2, unlimited Verizon wireless and a wireless tether app, I seamlessly run a 4G WiFi hotspot in the car. This allows me to use Google Maps and Google Navigation, voice commands, Tunein radio, Gmail, Google Calendar and anything else on the web.
I've been running this for almost a year and it is very tight. Of all the navigation codes I have seen, I still prefer Google Nav.
I just got the Malibu today. It doesn't have navigation (but the 7" touchscreen is sweet.) so I will probably use the Note2 w/ Google Nav as a standalone system.
