No sign of life in my unit at all, checked the fuse ,ok checked the harness ok. check car supply still ok, removed player still works fine when re connected..
This must be an internal fault on my d3, if so are there any internal fuses for protection to circuits? if not then who is the best to send it to for repair in the UK, I have registered the warranty on pioneer web site, but bought the unit new from ebay so cant send it back. Any advise on getting warranty repairs, or just pay up repairs not sure who to use. thanks

The D3 does not have a good navigation system in it, and because it is old and beyond its life cycle the fractional wear on the drive causes it to have trouble reading discs. Try cleaning the disc with a little water and soft cotton cloth. Do not touch the bottom of the disc after you clean it. If that does not work, then you need a new disc. You can try making a copy of the disc you have. If the program on the disc is good then you just need a copy that your unit will like. To make it simple.
Code? The parking brake wire needs to see ground to watch DVDs. You have to remove the yellow/black mute wire from the harness using a pick tool, then place that wire into the empty slot right above where it was, then ground it and the light green parking brake wire.
Your power antenna wire maybe hooked up to ignition. So when you turn off the car no more voltage is going to your antenna wire so your power antenna goes down causing a poor reception. You must hook up the blue wire on the radio harness to the power antenna wire.
Check all of your connections, due to the extreme heat and cold, the wires surprisingly are able to move quite a bit. This may trigger any loose power wires to disconnect from their points.
Make sure EVERY wire is properly crimped/tied down.
You also may want to check for any corrosion at your points.
Also there are a few shops out there that forget to scrape/sand off the paint to show the bare metal before connecting the ground.
Check your ground wire/harness that comes from the battery, if the wires are old the insulation may crack and cause a short to ground causing your electronics to not work until you restart it a few times.
Check to see if you have enough current to your unit. The best way to check is to take it out and bench test it. Most unit will shut down and try to start up when the current to it is lower than the minimum requirement. Goodluck.
Did you hook up the wire harness correctly? Because you are not receiving power to the monitor. check these connections again. Maybe you have the wrong harness. Are you using the one from your car or DVD player? Did you splice the wires together? Do you have a correct color scheme to your vehicles wiring? you may also need to bypass the monitor in order to view the screen while driving (if you're a rebel against johnny law)
Not sure what kind of connections you have, but be sure your unit is recieving good clean power. Try using another 12v constant and possibly a good 12v switched power source. Double check your ground wire as well. The unit may also be broken and might need service.
