The most important aspect of stereo replacement

November 13, 2014

I bought this with worries. I've read all of the Cadillac forums and blah blah I bought this and I have maintained all but my steering controllers (harness sold separately) great quality, a lot of wires but it's a diy kit that makes it super easy to wire up and plug and play. Chimes are retained all speakers work flawlessly. Make sure you purchase a antenna adapter or you'll have no radio.

I purchased harness for my Cadillac CTS, the product is OK. It works but not adopted to the metric system, I found out that it is not possible to switch climate control from F to C. Otherwise, the product is good to purchase.
