1995 Oldsmobile Cutlass Supreme

Verified customer (What's this?)
Verified employee purchase (What's this?)

I needed an antenna for a 95 plus and crutchfield tried to help me out. The antenna I received worked but the electrical element if it does not. In other words it doesn't go up or down by power. But st least I have an antenna

Pros: I can listen to music

Cons: I'm afraid to go through car wash !! Or that someone's going to snap it

Antenna Adapter

thedudeabides80 from Mount Sterling IL on 5/4/2014

1994 Oldsmobile Cutlass Supreme

Verified customer (What's this?)
Verified employee purchase (What's this?)

The price was nice and the quality of the product was great. BUT I was installing this in a 94 olds cutlass supreme and the factory antennae wire has a bend in it and would not fit correctly into this adapter, I had to go guy another adapter to fit into this one which fit into the stereo just fine, If your antennae wire has the factory bent end on the wire I would explore other options.

Pros: Great quality, price

Cons: will not accept factory bend antenna wire.
