Review: Amazing - Amazing. Lots of options. Ability to turn off auto start/stop on 2015 on up F150s but has the potential to do WAY more. Highly involved install and a must if swapping to aftermarket headunit to keep steering controls.
Review: Great tech support - The product and apps supporting seem to be solid and work as expected. The thing that impressed me the most was the tech support. I had a couple of issues with ApplePlay competing with UConnect and decided to give their support a try. Someone who was very knowledgeable answers the phone and was able to quick advise me on correct application. This is important as the product supports so many different variations of head units, cars, and installed features. In spite of the assistance I still has a minor issue with the final result, but about a month later they came out with a firmware update that applied to my vehicle and stereo head unit that corrected the problem. Which tells me they support their product after it ships. So many tech products these days don't do that. So overall I am very pleased with the product

Amazing. Lots of options. Ability to turn off auto start/stop on 2015 on up F150s but has the potential to do WAY more. Highly involved install and a must if swapping to aftermarket headunit to keep steering controls.

### ⭐⭐⭐⭐⭐ Great tech support

### ⭐⭐⭐⭐⭐ wow, this thing works amazing.
*by K***N on November 16, 2023*

What an amazing product with the most thorough instructions. In my application 2018 Subaru Legacy with the Harmon Kardon stereo with separate amp I had a lot of questions before starting. When you flash the unit it will have an instruction manual specific to your application, it is so thorough you need to put the seral number for the head unit in in order to flash the unit. Incase someone else is in the same boat as I was in you can retain the stock amp but you will only be using one set of preouts and they need to be the front ones( I found this out the hard way as the phone calls and other voices only come across on the front input), in my case I was not able to retain the factory mike but that is minor, there are two units bolted to the stock head unit you will need to retain both modules if you want starlink & eyesight to work. You will need to wire the power and several other wires but the instructions are very clear.
