I'm changing her radio because seh damaged her cd player, i couldn't find a cd module replacement but i did come across a few radios like hers but everyone from ebay is warning me about anti theft activation so i came her (forum) thinking the advice would be more reli...

Does anyone know if i replace a radio (am/fm/cd) in a 2004 vibe with another vibe radio (same model possible different year) will i have any issues with an anti theft activation ? If so....how do you determine if your vehical has anti theft installed?
