Hello site members.

I was wondering if anyone has installed a SIR-GM1 in a 2006 Uplander with rear TV controls at the head unit.

I have installed it but i am not getting a display on the radio
I can hear it on the AUX but still no display
I also do not see SIR 1 or SIR 2 when I go through the bands

This has been very frustrating for me, any help would be greatly appreciated.

Thanks
Don
