BUMMER! I had the PAC SWI-PS installed today, along with the rear view camera. I sat with the installer as he programmed the unit (he didn't mind, really). It was working perfectly, Volume up/down, Source and next track/Next preset, just what I wanted.
Then, an hour or so later, on the way home from picking up my kids from school, suddenly the volume became intermittent. I tried holding it down for a few seconds, multiple presses, etc.
Now, sometimes Vol up works, while down doesn't, or niether one works.
Any ideas? I guess I'll take it back to the shop and see if they can do anything about it.
Do you think this is an installer problem or a hardware problem, or maybe just an incomapability problem?
HELP?
