I'm not recommending this product for a car with steering wheel controls. I had to trade this in for another product to make them work. Other than that, no complaints.

Thing Turns My Headunit Off Radom Times And Sometimes Ill Raise The Volume And The Song Will Change!

I bought this unit to adapt my Tacoma's steering wheel controls to my new Kenwood receiver. Here's what I'd say:
PRO'S:
It works as advertised (most of the time).
Very thorough instructions.
CON's:
Tedious--> you have to determine what resistor you need (if any), pick it out of the kit via deciphering the resistor's color bars, break into the wiring, and solder the resistor/wiring into the harness. Why don't they just have a few pre-soldered & heat-shrink'd resistor assemblies with connectors on the ends that you "plug in" to the device. This could be as easy setting a DIP switch or even jumpers.
Needs to be "smarter" --> it doesn't seem to have the ability to interpret a "hold" vs a "tap." Many car's steering wheel switches/oem radios do have that functionality, giving each button more than one function.
Regardless, I love having the steering wheel buttons functional, and would definitely buy this again.

The installation was EZ. The unit worked perfect for 2 months, after that the unit gets confused. What I mean I like to control the volume and down on the steering wheel controls but it will skip tracks or go to the next track instead. Playing with it a few more times it goes back to working right. It seems that the unit needs to relearn the function over and over again. It does this by its self.

This adapter is incredibly laggy. not impossible to use once you get used to it; but definitely not like factory.

I can't speak for the install as I had someone install this. The functionality is ok at best. There are delays for every function pretty much. I am told that is how they work. Bluetooth functionality would have been nice too as my car has buttons for that too that are now non-functional. I am told by PAC that they have an updated version out now that allows for minimal Bluetooth functions now but too late for me now. Sonic was cheapest out there and their service was speedy and reliable.
