Mr Boston

I need a cd player bad in my 00 gsr, I found a 99-00 civic cd player on CL. Would this be plug and play? How would it fit in the dash? just like it would with a oem integra cd player?
Thanks for the help

It will not be "plug and play".
Your Integra uses the rear brace mounting system, pocket is attached to HU and both are held in place with two 8mm machine screws through a bracket on back of HU into a brace that is part of dash sub frame.
The Civic HU uses an "ISO" mounting system, both the pocket and the HU are mounted to "cage" with 8mm machine screws through the cage bracket into both sides of the HU and pocket.

The plugs themselves may or may not be the same, as the "old" plug was used on some Integra all the way to 01 and the new plug was used on others starting in 97/98...

With that said, it would not be a very hard mod to install the Civic HU into your Integra. even if the plugs are diff., an adapter can be made for about $20. with an adapter harness and a HU harness, both available from Metra/Scosche/Best and others. 94
