I just picked up a 1999 Chevy Blazer 4x4 for a toy... The stock head unit has CD and casette, but when you put a CD in it says ERR. I checked with the local chevy dealer and they said I'd need to replace it, and a stock HU is $400 from them... Screw that! Does someone have a stock Chevy/GM head unit with CD that they wanna sell? If not, what recommendations do you have for aftermarket head units? I will want to use the built-in amp because I have no room for additional amps or a sub... This vehicle needs to carry cargo! CD is a must. MP3/WMA would be nice, but not required. I don't care about cassette. AUX input is required. Preouts are not required, but would be nice just in case I change my mind later on. I really wanna stay $200 or under... But if you have a head unit that's worth going over, then please mention it. Absolute max is $300, however. I was looking at this unit: http://www.crutchfield.com/S-jnQgWq...id=morephotos&pi=1&i=130DEHP77D&display=L#Tab because it's designed specifically for the GM dash. Any thoughts on it? Also, what should I do about speakers? I figure I could get the head unit first and then see how it sounds... But if I were gonna replace speakers, what should I do? Keep in mind that I have no plans to add a sub, so I need decent low-end out of the speakers.
