I think my boyfriend has a Renault... I'm TOTALLY clueless when it comes to cars. Obviously, I will be able to check when I see him next but can I buy a car stereo for his car and will he be able to just plug it in? He's pretty good with electrics and stuff but is it like 'on e size fits all' or what? I want to get him a usb car stereo so that he doesn't have to burn cd's.
