Yes it is possible to put a single din radio in this car. Simplest way is to go on Ebay and order a single din radio fill-in kit and a factory radio wiring plug adaptor for the vehicle. Make sure you order it for the exact year make and model to be sure you have the right installation setup.

Sorry to say there is no fixing this unit. GM struck a deal with Panasonic to supply CD players for their DELCO radios. Panasonic is not releasing any parts for this unit so you can either find one at a salvage yard or on ebay, craigslist, etc... They are basically a "throw-away" unit.

No, replacing the battery is not your problem. Must be pure coincidence..
Tape is ejecting because the deck is faulty. Either a broken belt or a broken plastic gear assembly. CD players in this model were made by SONY and are troublesome. Rather than trying to get someone to fix it, go to your local salvage yard and see what they have. They are for sale on ebay also. They are basically "throw-away" units as SONY struck a deal with GM and GM can't supply replacement parts. PLUS... there aren't too mnay shops around that fix these units.

sorry radio is bad replace wu=ith one from a junkyard

It will work as long as it's for a GM cd radio but as mentioned it will have to be re-programmed by the dealer.

If it's an aftermarket cd player, you'll require a separate module harness with a relay circuit for the airbags and tach information to function. Or you can purchase a re-location kit which allows you to locate your factory radio into your trunk to hold those funtions. The re-location kit is a fair bit cheaper than the module. It's stupid that GM would design a system like that but that's what you'd need.

remove the negative side of the battery then remove the radio/cd player take the face plate off to get access to the CD
