Hi there
that is a big system
well common problem with feedback is the power wires connected to amps and the RCA wires run from the pioneer unit to the amps are too close to each other if the power wire from the battery to the amps are run down (left) side of car make sure RCA and remote wire are run down the (right) side of the car if this is done like this than it could be the RCA cables you are using the other thing is if you rev the engine does it get louder if this is the case then the noise you hear is the alternator of your car to get rid of the feedback look at your amp power wire and load it with electrical tape or buy a piece of dynamat and place it around the amp power wire this will stop that...........if what i just said doesn't happen when you rev engine than ground each amp to its on metal frame (do not ground them together) this should also stop the feedback. make sure all RCA cables are no where near the amp power cable from your cars battery
hope i was able to help

There could be a feedback loop occurring, which would cause the loss of those lights. Disconnect the DVD wires 1 at a time and check for the operation of the affected lights. when the operation is restored, you may have found the culprit. Now reconnect the other wires and check again. If all works right, then that wire is the one that needs a Diode installed inline to stop the feedback and break the loop ( the Diode HAS to be installed correctly as it is a 1 way gate of sorts ) . It is also possible you may need to ground the player to a different ground. Running a wire under the dash is labor intensive, but could also solve your problem.
Good luck and thanks for using Fixya!!

I have a fairly good sound system in my jeep cherokee, new speakers, deck, new battery, rca cables, and a new box for my subs. But recently i've been dealing with some problems. i've had my amp grounded...


there are really only 2 causes for this.

  1. grounds. Make sure the grounds are clean and tight and all paint and dirt was removed before they were fastened.
  2. Your alternator is starting to go bad.
I would lean toward the grounding problem as you have said you just changed them. Also make sure the grounds are as short as possible.

Volkswagen Passat Factory Stereo


If I remember correctly there should be 4 holes on the face of the stereo. 1 in each corner, sort of. You need to get the removal key for your VW. It should look like somthing like a U. You should be able to pick those up at a local store. I think one time I even saw walmart had them. Another option would be to stop at a stereo shop and see if you could borrow the tool or let them take it out, but it might cost money any way. Then once you have the tool insert the keys until they click then, in a way, spread them and this should push the clips in and let you pull the radio out. Good luck.

Repair


$250 is a bit tough if you are sure the IC is only $27. It is not clear from your post if your microprocessor works alright. If your display and other functions were okay when you gave it to the service guys, your micro is okay, in that case the only other costly thing in your board is output ic. Getting a board from Pioneer isn't easy, they don't sell boards in shops, they provide it to their authorized service ceneters only. You can try finding a friend who is aware of the boards and have this checked.
