This thing is giving me **** again, either the woofer won't turn on or it won't read CDs, but the best thing is when I turn on the car the CD player display will almost always stay unlit unless I tap the screen. Fairly hard. I've even smacked it before. In fact I've had the woofer turn on just by slamming the glove compartment. I tried the CD cleaning thing, a CD with little brushes on it, but even that isn't a long term solution.

I want to remove the Bose headunit from the panel, take it apart and clean it with electrical contact cleaner, sort of like the kind used for the MAF sensor. And clean the connectors. Will I mess up the system this way? At worst I would like no changes at all, and at best an improvement.

 

Took out the Bose headunit from the console, took it all apart and sprayed everything I could fit that straw into with electric contact cleaner. Then I let it dry and reinstalled it.

Now the buttons are responsive, the screen doesn't dim even at ignition, the volume button doesn't stick and... the sub is BACK.

Highly recommended to anyone with this Bose system. I don't have the 6 CD version, just the regular one, but it should work the same.
