Pioneer DEH-P4800MP head,GEX-P920XM reciever,Terk XM 9000 antenna.My radio will lose XM signal in wide open country with no physical interferences (trees,bridges,ect).I travel the entire country and the it happens mostly around large metro areas.The I20 coridoor at Dallas/FT.Worth is the worst,but it'll do it anywhere.Once cleared of the area it will work fine for hours.All connections are good and I've reset the reciever twice.Basically all I get from the vendors are blank stares and shoulder shrugs.Two of my buddies have Alpine systems with no problems.Is Pioneer just a piece of crap? PLEASE HELP!!!!

The problem is amazingly simple.
The red wire goes to your ignition so it turns the radio off when you power down your car so as not to discharge the battery.
The YELLOW wire is usually your memory and it connects to the power side of your fuse box (anywhere will do as long as it's powered when the car is off completely). Occasionally this wire is blue but it's rare.
This wire draws a tiny little bit of power so your stereo doesn't 'forget' your station settings etc.
BTW Pioneer is one of my favourites :)

Broken antenna cable. Likely you have a kink or worn thru point on the wire somewhere.

your sure connect antenna is bad that is why you get this message or you have something hooked up wrong check the power and ground on the unit if it has one .... some have it, some dont but most of the time its just a bad wire

Every time I turn off my Pioneer POS I have to refresh my radio. It keeps losing the channles so I'm left with only a dozen or so channells, none of my favorites. I have two other radios that don't have this problem. The others are not Poineer. XM tech support is horrible. They told me I need a new antenna. I asked how changing the antenna would keep my radio fromo losing the signal in 10 seconds and they had no answer.
