hi, just wondering if anyone knows if it is possible to upgrade from a Cd400 with Bluetooth to a bigger unit with Sat Nav, preferably a cd600 or cd900, is there additional wiring, heard its meant to be a very hard and costly upgrade, but wouldn't mind an aftermarket android one. is there certain ones to stay away from or certain brands i.e Sinosmart ect thats more reliable?
any advice would be greatly appreciated as this is doing my head in
Thanks
