Worked great

Written By TSub, Central KY on Tuesday, January 29, 2013
 
This worked great for taking my Suburban back to a stock radio. The adapter made it easy to put a factory style radio back in since the antennas are somehow different. Had no issues with loose connections either.

Don't Know Yet

Written By Billy M, Sumrall, Mississippi on Wednesday, January 02, 2013
Installed in a 2006 Pontiac Grand Prix
Crutchfield Customer Review (What's this?)
 
Had to use this with an adaptor for FM modulator of iPod. Did not fit very tight on a GM radio. Still works, but it seems like if ever hit a large bump in the road it's probably going to come out. But I may be wrong.
Pros:
Works, so far.
Cons:
Fits loosely in GM radio.

Antenna Adapter

Written By Michael, Flagstaff AZ on Saturday, February 21, 2009
Installed in a 2004 Chevrolet Malibu (Classic)
Crutchfield Customer Review (What's this?)
 
Why does GM use a weird miniturized Motorola antenna connector? Dunno, but they do. This is the answer (or if you are installing an XM modulator in-line, it is half the answer.)
