Recently had my car serviced requiring the battery cables to be taken off and reattached. As soon as I drove off the lot the Alpine head unit was no longer able to recognize the Sirius tuner. I still can see the iPod connection that goes through the interface but no Sirius. I've looked in the unit and am getting the following orange light sequence: 5-6 short blinks on circuit R24 and then 2 long blinks on circuit R28. Can anyone tell me what this is indicating?
I have already checked and replaced the fuse, disconnected and reconnected the interface/tuner unit, verified I'm getting power to the unit, reset the head unit, and checked and changed all head unit settings that could be relevant but no luck.
Hopefully one of you Pros can point me in the right direction other than buying a replacement unit.
