Prepare for loads of fun and lots of run-a-round. I have an 02 SE and was told similar things by different shops, it all depends on which radio you have but be prepared to lose some car functionalility. If you have the TRUE ribbon cable you cannot remove the radio from the car, you will have to get a dual location harness. This harness will allow you to install an aftermarket radio in the car, but will require you to keep the GM radio in the trunk, or elsewhere to retain some vehicle function. I was lucky, and that I did'nt have the true ribbon cable. The only features I lost were all the damn dinging.. and you can purchase a device called a "GM Chime" from another company to replicate that. You will lose the ding for open door, lights left on, and low on gas, etc. It may be cheaper in the long run to get a CD changer with an FM modulator (uses car'* antenna). If you really want to replace the HU try another car stereo shop that is'nt a chain, they usually know better, I would ask if you could remove the stock radio and take a pic of the back so I could tell if you it is similar to my radio, but I dont know what that would solve.
