Technical Installed radio in car

[MichaelD88]

when i tune in the radio stations and save them (whilst engine is running) next time i start engine the radio stations have been cleard so i have to retune it again. this happens everytime i switch engine back on after i switch engine off. could this be an electrical problem with the car?

any info will be great. cheers

You need to swap the power supplies over, I think its the yellow and red ones, use a meter or light, or if all else fails read the faqs/guides.
