i dont know anything about cars. but the head unit (which i JUST learned what that was) is a peice of crap. my cig lighter doesnt work. i cant charge my phone or listen to anything but the radio. i wanted to install a head unit that has an aux port and a USB port. i figured i could find one for about $100. its really all i have and i cant afford new speakers or anything right now. they seem to be fine though. i guess my question is, if i purchased such a head unit... will it be possible to hook it up to such an old car? any tips on beginners? i just want to be able to charge/listen to my phone. i dont care much for fancy or speaker quality at this time. only bc money is an issue.
