For some reason the head unit with the navigation completely restarts itself. Sometimes when it comes back on the display looks normal but there is a low hiss and regular pop sound about every three seconds coming through the speakers. It seems I can jiggle it (screws are now out) and make it restart again and come back on and functioning as normal. Has anybody experienced this?  It happens whether the fiber optic cables are plugged in or not, although of course I can’t hear the audio effect. It’s simply darkens and brings back the display and backlight. On its own.

I experienced this right before my unit died for good. You can find good used units for not too much but you may wanna consider a rebuild or an  aftermarket unit as well.

Something deep inside me says i will face the same thing. I'm thinking to do a factory reset but im scared if it will ask me a pin number and i dont know where to find it, also i will blow it in case it has dust inside.

No the reset combination of pressing keys “148” simultaneously will reset the unit without a PIN required

Even if you do a “factory restore” from the sub menu no PIN is required

Thanks. I kinda thought so. Do you have a source suggestion for a rebuilt one? That would be a more known good unit.

Another question: it sounds like you replaced it and all was fine. Is that the case? I was concerned it might be a wiring problem and replacing it wouldn’t do the trick!

I have replace mine with a used unit. Simple plug and play. That was about 2 years ago. Haven’t had a single issue

Can't say for sure. With it restarting it originally sounded like a loose MOST connector to me. They are crappy connectors and if you have anything aftermarket like a Mobridge, IPod adpater, etc... it introduces more connections. The thing that I am not familiar with is the popping. It may be a failing unit. I do have a late ('08 manufactured unit, out of my '06CTTS in good shape (Shameless plug, haven't bothered to Ebay it.)).  One thing about a used unit. You will loose or gain with whatever the replacement unit has coded. If you have Bose, you need a Bose unit, if you have Nav, you need a Nav unit, or both, etc... You could possibly loose or gain SAT, off-road package, Compass, etc... depending on how the replacement unit is coded. I lost the dash compass when the dealer replaced mine but didn't notice it for a few days and since they were 1.5hrs away I just accepted it. You can of course have a dealer code a replacement unit for what you want but that still will cost extra $$'s.

Definitely pull your unit and check all connections first before spending the money on another unit.

Thanks everyone for your responses. This has been a big help. Although I still have to decide whether to replace or get a new aftermarket with Car Play.
