Works great with Metra 99-7864 dash kit

Basically this adapter was plug and play and worked great with Metra 99-7864 dash kit. No complaints at all. Was simple to use and the included instructions were laid out well enough to describe any issues one might have. I definitely recommend this item.

Works great

Quality product,I ordered with a Metra installation kit and both worked flawlessly.Sonic shipped very fast and the harness makes installation a snap,especially if you decide to put the factory stereo back in at some point.

Perfect Harness

Al wires on the harness were pre stripped and easy to identify with my additional harness I bought. Would recommend to anyone who’s car this fits in.
