i have a 2001 audi tt which originally had the concert 1 radio, I converted to a concert 2 radio so I can use the oem iPod kit from audi which is for 2002 and up tt.

The radio only restarts if the ignition is on or the car is running, but if I just turn on the radio it works fine, thanks again for your help, hope my description can help figure out the problem. Kufatec can-bus emulator for concert 2 radio, radio reboots with ignition on or car running
