Audio Systems: OEM radio swap

Question
Hello,
I have a 1999 Buick Riviera that is starting to have issues with it's factory radio/cassette/cd player. Would like to go ahead and purchase a replacement OEM unit for future replacement. Wanted to make sure that part number # 25727524 B 2000 is compatible? Or if you have other suggestions? Thankyou very much for your time.

Answer
no that is not the correct radio i believe tha part fits the Le sabre

this is the correct radio for your vehicle

some Buick radios look the same at front but the plugs are not the same
