My 1996 Alfa Romeo 146ti has a Pontus PAC-7002(B) stereo, probably aftermarket.
It has a removable MP3 player and a built-in CD player. The whole interface seems to be locked, possibly as part of a security feature. The volume control works but none of the buttons operate. I put a CD in which plays automatically but I can't skip tracks or switch to the radio or MP3 player.
I can't find any information on the Internet other than that Pontus was part of Hyundai Autonet. I didn't receive the manual for the stereo with the car.
Has anyone used this stereo or got a manual for it? Any tips on how I might reset it? I've tried unplugging the power harness for a while to no avail.
