Actually, it was the custom shop that messed it all up. Eslai is right, you don't need a fancy head unit. I would recommend a single DIN with either an Ipod or Front AUX

They will have to by-pass the stock amp which is not that hard. I actually had Best Buy fix the mistakes the custom stop did (it's a long story). If you're on a budget, I would only replace the door speakers and not the dash speakers.

The doors are just woofers. They will sound muffled if you keep the OEM speakers in. Other than that, you'll have decent highs and mids but no bass. It's not my daily driver so I really don't care that much about the sound. Good luck.
