DEH-P7900BT display issue

I installed the deck in my 99 dakota, everything worked fine. After about 3 weeks the display started acting strange. About once every min. the display will reverse (posative to negative) for about 10 seconds then go back to normal. This happens in every mode including when the deck is turned off. All functions (tuner, ipod, BT phone, CD) work just fine. At first I thought it was searching for a BT signal or something so I went through the entire setup with no success. I took it in to the place I purchased it and after they did a "hard reset" on it they told me it was probably an installation problem. I find that a little hard to believe due to the fact that it didn't do it for 3 weeks prior. Any suggestions that could solve this issue?

Hey....alll you have to do is hold the "sourece" button until the unit shuts off, then push the wheel in until a menu shows on the display. scroll over until you see the "reverse mode" option...simply push either up/down or left/right to turn this off!!! NOW UR DONE!

That fixes my problem too - I was afraid something had gone wrong when it started happening. All is well now. You guys are great.

I would be willing to bet There is a problem in you detachable Keyboard. I would go to Dealer and see if they will let you try one from a different stock unit they have to help isolate problem. This part would be covered under warranty if radio is taken to a Authorized pioneer service center.

I would have an auto parts place put their instruments on the alternator to see if it works. If a Dodge isn\'t charging properly from the alternator, one symptom will be the guages will act like they are crazy and the speedometer will flip back and forth like its crazy. If your car isnt charging the battery, your car will recover some charge overnite to start in the morning, but a faulty alternator can suck the battery down while you drive, and kill it prematurely. Auto Zone or Oreilly\'s or NAPA stores will usually let an employee go out (during daylight) and run the codes on your car computer or wheel their battery/starter/alternator cart out to put the tests on your car, for free.

Usually a sign of something draining the battery.
The machine test probably showed the battery could hold a charge and the alternator was charging the battery.
You may need to have someone check for a power drain.
When the key switch is off, there may be a weak short to ground or a relay or component that is using power.
