Problem With New Radio

[killie77]

Hi

Decided to replace the Radio cassette with a new CD Radio

Installation was no problem fits well sounds good. However the memory on the presets

don't seem to be working also when I switch off the radio,leave the car come back and open the Car by using the remote fob the radio switches on ?

So I'm wondering do I have to swap some wire's over on the New Radio ?

Thanks for any Help

Regards

Ian
