Hello everyone. I bought my mom a pioneer deck for her birthday and I have been reading you can't install a deck without a additional harness. She has an 04 bottom of the line deck just a cassette player no steering controls. And I don't think she even has factory amp. Where would that be? She doesn't have on star either. Any advice can help.

 

Ull need a modual to retain all ur warnings, everything in these cars are controlled with the radio, ill post a link for one, walmart sells em too

Correct, you need an interface harness. If she has an amp, it would be under the rear deck in between the 6x9's.
