No problem installing it and it seems to work fine.

as long as you have the newer version ( with front mounted controls )

Easy enough to install, but lacks a variety of nuts and bolts, custom fittings, with the brackets to fit properly with my Samsung LEDTV 32".  I need a longer rubber cylinder spacer for both sides, the pair included weren't thick enough, which requires me to search and locate and buy other parts.  It seems unnecessary if I buy a wall mount, I assume it would include all I need for many different standard configurations.  Particularly, I own the Samsung LEDTV 32in, which seems quite common.  If this didn't include the necessary part for a good fit and install, something seems not right.

Installation can be a pain depending on the space that you have. The bigger problem is the extra pin on the cable. Take your time and read the forums to know how to do this right. Once done it worked fine.

I installed it my self.  Yes it takes a while.  If I have to do another it should be easier.  There is a learning process to learn the best technique to install.

Not for rookies to install. Fine product once configured properly.

Works good but needs to be integrated into the system as a scene.

A bit difficult to install if you have a bunch of wires in the box.

Still hard to install (it took two of us), but it works. The line may be too short to last long.

make sure you have a place in your car for it before you buy this.

Purchased device to add/expand my currently alarms system monitored by a nationwide alarm monitoring company. I asked if I would have any issues pairing with my current system and was told no problems. After receiving the item, an installer code is needed to pair with my system. Was not able to use device and had to return.
If you can pair this with your system, I believe it would be a good addition.

not everything will work perfect or fit great some stuff you will have to fab for it to work. But a lot of different looks and designs of Headlamps/marker lights, grills, taillights etc.

We had some trouble installing this. For the diy, you may need to utube how to install the so-called easy to install clip thing. It wasn't intuitive.

Works as advertised, but can be a little difficult to install - but maybe it's just me.

My installer like these bolts, he said the included tool really didn't add much but in a different situation it may be usefull

installation is fairly simple for those who are willing/interested in doing it themselves.  Once installed, theres a second "cd changer" that just operates you bluetooth connected device.
