Heya guys, need some help again ;) I'm installing a Pioneer GEX-P900XM XM receiver in my girlfriends 1999 Eclipse. Before I did anything, the HU worked just fine. After I tapped into the power wire (power wire ONLY no others were touched) the HU clicks on and off when in tuner adn CD mode. When in demo mode, or XM mode it stays on indefinately. However, when in XM mode, it shuts down when i turn the volume up about half way. Whenever the power cuts out, its not a hard cut off, its a fade out, but fades real quickly. ANY ideas are appreciated as always!! Thanks!!

sounds like you are tapped into something other then a constant power wire.
do you have a test light or better a test meter?
if so then test that power wire and see if its getting a constant 12volts when car is off and a constant 13+volts when car is running.. if not then thaqts where your problem lies.
also in my opinion though not 100% sure sounds like you make have taped into a dimmer wire or other wire that supplies 12 volt but not constant....
also check to maek sure you have a good ground directly to body or firewall... you would not belive how many head aches of problems can be tracked back to a faulty ground...
i'm sure ttocs or swez well have a huge pool of idea to help you along but this should at least get you started in the right direction

Most of the newest model HUs are now recommending their own seperate 10-12 gauge dedicated line to the battery for the power source (constant) I would first recommend this, then a tap into a switched wire under the dash (easiest to find right before the BCM) this will usually be a 10-12 gauge pink, yellow or brown wire depending on the vehicle... you can also use the preexisting switched wire on the factory harness from the origional radio.. The switched wire does not pull alot of juice, it is more like an amp remote wire to the radio instead of an amp. Letting the radio come on only when the switch is in the ignition. And last but not least ground the radio to the chassis. This will save alot of grief in the long run.
