This interface is designed for vehicles that have permanent and ignition power feeds in the ISO connector in the dashboard.
Some cars only have a permanent power supply and use the CANbus signal to turn on the radio, for these cars a separate ignition power will need to be supplied or use our 29-655 interface with switched 12v ignition

Fits the following Alfa Romeo vehicles:

147 (2007 - 2010) CANBUS vehicles only

GT (2008 - 2010) CANBUS vehicles only

There are small amount of cars pre-2007 that have CANBUS ignition. Before ordering please remove the original radio as the vast majority of original radios have a useful wiring diagram on the chassis. Remove the original radio and check, if illumination and switched power are showing on pin 2 and 3 of the diagram then it does not have CAN ignition and 29-655 is the correct interface for you:

If Illumination and switched power are missing from pin 2 and 3 of the diagram then the car uses CANBUS ignition and will need interface 29-655-CAN:

NOTE: on some cars, the steering wheel control wires are reversed, check and test for correct operation of the steering wheel controls before installing the new radio in the dashboard. If they are not as expected or reversed then the white and grey steering wheel control wires will need to have their positions swapped at the interface box.

If the car is fitted with a BOSE sound system, this part must be used in conjunction with 20-266 Alfa Romeo BOSE interface.
