The parking brake (light green) connection needs to be connected to a (-) ground (black) wire, not a +12V wire. While it won't damage the unit to put +12V power to that wire, it does need to see a (-) chassis ground to view video while in motion. If changing this wire to ground still doesn't offer the solution, your Pioneer may require wiring of a relay as is necessary on several newer Pioneer navigation units. Some Pioneer radios will still not allow video to be viewed even if the parking brake wire is grounded. For these units, I recommend using a standard 12V automotive relay (Bosch type). I would recommend consulting a professional installer if you are unsure about wiring this relay. Otherwise, if you are comfortable/knowledgeable, the instructions for wiring the relay are as follows: 85 - chassis ground86 - Blue/white stripe (remote turn-on lead from Pioneer)87 - chassis ground30 - Light green (parking brake lead of Pioneer) The wiring of the relay will cause the parking brake lead to see the ground wire at the same time that the Pioneer actually powers up. This delay can be necessary for viewing video. An optional timing device can be wired in to do the same function such as PAC electronics' PTR-7. The message that you are receiving for "screen image may appear reversed" is typically only visible when a reverse camera is used. For this, the Pioneer has a separate purple/white stripe wire for +12V reverse input. I hope that this information was helpful.- Elliot
I will assume that none of those wires are marked, thus leaving you with the cumbersome task of tracing each wire to its place of origin and properly marking them.
I will also assume that you have a standard hardware configuration whereas the in-dash head unit serves as an input selector and pre-amp for your aux.CD/DVD unit.
A possible shortcut would be to first identify the two power leads( one is a constant 12+ volts & one is a switched 12+ volts that is a remote power lead from the head unit) and the ground that was ran to the missing amp, mark and separate those from the group. Then with a test speaker trial and error those remaining signal (speaker) wires with the in-dash CD player on and loaded so as to find that units signal outputs (there may be more then one pair) You will need to identify left and right output signal pairs by adjusting the head units L & R control and marking those wires accordingly. Next with a pair of signal leads with output, temporarily connect them to all of the other unidentified signal pairs as to determine its speaker and marking them accordingly. At this point you should be able to make your left and right speaker connections.
Note: it will be wise to have a DC voltage tester to check for the missing amp power leads and signal polarity especially if you plan to install a new amp.
to install this unit in your car........as a beginner i would strongly recommend buying a aftermarket radio harness (this harness will attach to the wire plug in your factory deck simply unhook the factory player and attach this harness to the plug you just pulled out of the factory unit) once this harness is installed on the factory plug it will be a simple colour match (just attach wires to pioneer wires IE. red - red, white - white........once all the wires are attached install in dash recommend buying a mounting unit for this net part it will hold the deck in place in your dash...........after that is done install your pioneer unit push it in place apply power by turning car on..........pioneer deck should turn on and work if it does not turn right on look for a source button on the pioneer unit and hold it down till the unit turns on
hope i was able to help
OK on the nav side it's not the vss wire the is to just tell the avic you seep for off road use to nav track your rout. in the nav menu it should say gps ant or sum thing like that it will tell you how Meany sat it sees that should tell you if the ant is broke or not
GM's Door Chimes Are built in to the stock radio. You need to buy a door chime relocator if it really bothers you. They Are about $30. I got one but the chime it came with was loud and annoying, so i cut the wire to the tiny speaker the relocator comes with just so didnt have to hear it. So, if it really bothers you, go to your local car audio store and ask for a door chime relocator for GM vehicle, they should know what you are talking about.
