radio memory probs

[joetyler]

my headunit wont save any of my radio station presets, ie, if i tune it to radio one it is fine until i turn the car off, and then when i start it up again the radio stations have all been reset. wondering if anyone has any ideas. it is fine if i have it playing a CD though, it remebers where it was last playing, any thoughts??
Cheers

You need to change the +ve wire and the ignition wires round.
(the red and yellows wires)
