paid to have it fitted coz the harness that came with it was wired all wrong, the software i found on the net for nothing so just cost me the price of a micro sd card.
happy with the overall function of the unit, next thing is to fit a wireless rear view camera
the DVD works well, ipod connection also charged my 4gs iphone BUT when using my phone in the bluetooth mode my contact list is messed up although it works with the wifes sony ericson so i think its just an apple problem, making calls is clear with the microphone that comes in the kit
all in all a cheap sat nav/bluetooth/DVD/radio/CD/ipod combo that (touch wood) works well(paid £349)
