I just installed my new one and it is working a treat, it came with all the right cables, the only cable I need to terminate myself is the ANT. It has been a long time since I last installed a system as my last system was solid so didn't need changing. I can't remember if the ANT cable connects to the AUTO ANT cable or a permanent 12v. Also the DI SENS pin is missing, not sure if this needs to go to anything as the unit powers up fine.
So far I have tested:
The AUX port that was already fitted to my centre console by Audi works fine.
The SatNav is iGO8, looks like its working fine but haven't hooked up the GPS antenna yet.
Bluetooth allows me to wirelessly play music and it has downloaded my phonebook so it shows me who is calling and allows me to call from my contacts list.
Radio reception is poor but I haven't hooked up the ANT cable yet, I assume this powers the aerial amp to provide better radio.
I am sure you will enjoy it mate, looks the part, slight downside is the white buttons during the day but at night they are illuminated red
