I have a sony xplod cdx gt210 and i've got everything to work exept the memory, it won't keep radio stations set. is the blue wire on it for memory ? the wiring ain't makin sense either, wether i have the red wires matched and yellow wires matched or switch them it still works and turns off when i switch the key off. i'm confused... i have a 94 ford f150 xlt 5.0 v8.

This is happeneing because the stereo does not have a battery power connections. The yellow wire is for a constant 12 volt connection. This connection is for the stereo's memory.

Hi,

their should be a blue white wire on the back of the radio. this wire is called the amp turn on wire connecting to this wire will provided 12 volts when the xplod cdx gt520 is turned on but if you press the off button on the radio the 12 volts will drop to 0 volts but when the radio is turned on the 12 volts will come back.

I think you're asking for the switched/ignition wire which would be the red wire on the Sony harness. Also you could try the blue (remote/antenna) wire. The manual can be viewed/downloaded here.

Hope this helps

you need to make sure the yellow wire is going to a constant voltage source. (always hot).

you have the remote turn on lead connected to the wrong wire. connect to blue w/ white not solid blue (its for power antennas)

Start with checking the antenna has an earth connection.

did you buy a factory radio connector to connect the old harness to the new radio wiring if not you can get one at wall mart for 20 dollars and it will be color coded

fm radio stations only broadcast on odd numbers. there is no such station as 107.0 only 106.9 or 107.1
