Easy fix, There are two 12+ volt feeds that should be connected to your unit.
1. Constant feed = 12+ volts that supplies power to the units memory all the time.This wire can be connected from the original radio connector wiring so long as it supplies constant 12+ volts, or be pulled from the battery, with an in-line fuse.
2. Switched feed = 12+ volts that only supplies power when the ignition switch is turned on,This wire can also be connected from the original radio connector wiring so long as it is a switched feed, also with an in-line fuse. 
During installation ether these wires were swapped or the constant feed (memory wire) was not connected.
Good luck...

Radio sound goes on and off--the closest radio stations won't even pick-up. If you bump the side of the unit it will play GREAT for a short, very short time just fine then back to on and off soun


sounds like you have a loose wire, what wires are you moving under the hood... do you mean behind the head unit? i'd trace each wire individually until you find one that has a poor connection, if they have wire crimps on them so you can't tell, cut them off one at a time and re-crimp them/twist them together.

Everytime i start my engine none of my radio stations are stored. and the angle doesnt go where i left it before also the screen doesnt closed when i turn the car off.. please help!


The constant power wire either wasn't connected, has come loose, or was connected incorrectly - as in connected to ignition instead of battery power. Check your red and yellow wires to insure they're connected correctly.

I have a eclipse avn7000 and apparently I put a cd in it that the radio cant read, and it wont let me eject. I can hear the radio trying to read the disk at all times unless power is off. Is there a reset...


There is a reset button just to the right of the CD slot, it looks like a reverse dimple. use a ball point pen and push it in and hold for 3 seconds. when you release it, all the settings will go back to default and you will loose preset stations, however, it should release or play the disc. Hope this helps

Preset radio


The best way to do this is to be very patient. find the station you want to preset and simply touch and hold the number you want to save it at on the touch screen. the station will pause for a split second and then you will see it on the display of the presets

You have it wired wrong. The red wire goes to the key switch and the yellow wire goes to the battery or a constant hot wire.

Good Luck and please rate

When i turn on my car (vauhxall corsa) i am able to programme radio channels to the buttons, however when i remove the keys from the car i loose all power to the radio and also when turn back on i loose...


There's a wire on the radio that connects to a constantly LIVE 12V circuit. This wire usually has an inline fuse. If this wire has become disconnected, or if the fuse blew, or if the fuse supplying the area that this wire is connected to has blown, you'll lose all memory capability on the radio.

Check the fuses in your car's fuseblock for a blown fuse. If you can't find anything blown, check the inline fuse described earlier. My guess is that you'll find one of these is causing the problem.

Let me know what happens. Please rate accordingly.
