Pioneer Head Unit not storing stations..

techguy

My friend has a pioneer head unit in a 98 polo and it wont store any of the radio stations that are saved by him. I did do it right btw (Holding down the number you want to save to)
but,when the key is taken out of the ignition the radio reverts to default, you have to retune the radio when it is turned back on. I am sure it is something to do with the wiring because it was not originally in the car. Probably a realy or something but is it easy to fix or not?

Thanks

When I bought my old 306 i had an upgraded radio installed and it had the same problem.
I left it in and it turned out to be the wiring all right.

Probably the wiring. There should be two 12V power lines coming into the radio. One is switched, i.e. it goes on and off with the ignition switch which powers the radio itself, and the other is always at 12V regardless of the state of the ignition switch. This second one is what keeps the memory for the stations intact when you switch the ignition off. Maybe somethings come loose or fallen off behind the radio, or maybe a blown inline fuse in the permanent 12V power lead?

I just fitted a JVC in my Corolla and had the same problem. Was definately a power wiring issue as soon as I changed the cables it sorted it.

Get the manual off the web and it will give you the details.

Yeah, look for the two positive wires in the back of the radio...

Yellow - Usually the switched power..
Red - Usually the constant power..

I think this is correct, I'm sure i'll be corrected if I'm wrong though
Also stress usually, as the colours may be different in every car. But you should be able to just switch the two and all will be fine again.

had same thing a few years ago, and it was exactly that.

ended up using a line of the cigarette lighter socket as the constant power, as it's always got juice going to it.

Warning! This not always the case. I've had cars where the cigarette lighter socket was switched too!

before you go ripping out the stereo check your fuses that was the problem on mine

I'm having the exact same problem with my new Pioneer Stereo in a Polo. The red is the switch live and the yellow is the permanent live, I have it connected this way and it won't store the stations. I switched them around and the next morning I had a dead battery. Perhaps someone who has there's set up correctly can let us know which way they should be? Then all I have to solve is my rear speaker problem.

Thank god for that it was like that on this polo also but i didnt change them,I must get the model number and check the wires...

You just need to switch the yellow and red cables around in the connector from the stereo to the ISO block. Mine's working perfect now.
