I have a 04 impala ss with a cd stuck in it it only has a cd player want to know can I get a headunit from another Chevy to use and if I find one with the tapedeck and cd player will it work the same also i have satellite radio which i don't use can I buy something to to use the output for the satellite radio to play mp3'*

It is possible to swap decks around, but I believe you may run into the VIN issue. On newer cars, the radio will communicate with the PCM and verify that the VIN programmed in the radio, matches the VIN in the PCM. Dealers can reprogram this, but it will cost you. No match, no worky.

Do they even make tape decks anymore?

Without actually looking at the radio, I cannot say if you could connect an MP3 player to it. How is the sat radio connected?

Its all factory and another issue is that the radio is also the control for resetting oil life ,low tire and settings for keyless entry/alarm if I replace with after market next time my change oil light comes on how would I reset it or if I replace radio would the change oil light not work anymore

I have to change my signature also I just got the car

Oh, that part I'm not sure of. Guess we will have to wait until someone else more familiar with your system chimes in.

judging by the fact that you use the radio to reset all of that, id hazard a guess that it does indeed have the vin verification. as for tape decks, they were an option untill they brought in the new body style. (it was a very rare option though so you might have a hard time finding one) if i were in your situation, id go pick a junkyard unit and see if you can swap the cd decks. it would probably save alot of time and money.

i do see some with tape decks and some without but what has me lost is most gm radios look the same from 00-05 but if the car i get my radio from doesnt have a feature that mine does will it not work like if i get a radio out of a 04 venture will it work and i still retain everything thats in my current radio

i had a 03 monte which is all the same, i put a aftermarket head unit in with the kit that retains chimes and that. the oil life you can reset by turning the key to run and pushing the gas petal all the way down three times fast. the rest of the options arent frequent things that you need to change, i just kept the oem headunit and stuck it back in if i wanted to change something. and if you wanted to sell that or buy one from the jy it would have to be programed by the dealer which makes it alot more cost effective and a million times better sound quality to just get a aftermarket unit like i did. i dont care about the chimes when i bought my 07 i didnt even get that just the 10 dollar wiring harness from ebay and am much happier without all the noise all the time.

cool so the oil light was the biggest deal for me like you said the rest are things i'll probably never use
