Looks like there aren't enough positive mentions yet.
This product is horrible. It was installed by a professional tech in my CTS and didn't work. Had to make another appt. 3 hours later - still didn't work. Another appointment, sent to another store. waited 4 hours. FOUR hours. Guy said he couldn't duplicate it, so it can't be fixed. The mute button turns itself on at random. The source changer flips through the sequence at random. Do not buy this. I'm 8 hours into waiting for them to fix it. Any longer and they'll give me a blue shirt and nametag to wear in the store. I'm sick of calling to get it fixed, but I'm also out lots of money so am stuck either way.
No, I would not recommend this to a friend
