I had troubles programming it to my car and finding clear information on how to install/program. Make sure you go to the idatalink website they have a ton of how to videos, and **YOU MUST GO THERE TO FLASH THE MODULE** **YOU ALSO NEED THE DATA CABLE FOR A COMPUTER IT DOES NOT COME WITH IT** But for someone who knows the basics to wiring and has never installed a remote start before. I figured this out rather quick, until I didn't know that I need to flash the unit with the programming for my vehicle. It makes since but the instructions don't tell you.

Williston store installer said this was the one to get for a Audi A3. Works great, much faster to install. With the 2500' remotes, can start the car from inside a building and car parked a long ways from the grounds. Great unit.

This is great simple plug-in play and you can use the current remotes the only downfall is the range is really short so I had to spend another $80 how to get a 2500 foot range extension but now it's awesome.

I looked into getting a Viper remote for my 2015 Passat, cost was about $600 plus my key fob, either purchase another one and have it programmed or give up a spare. Total would have been around $800. This Compustar was much cheaper, didn’t have to sacrifice a key fob and works just as well using the original fob. Another plus, installation was free.

Was so easy to install that I thought there is no way I did this correctly! It was a very easy plug and play in my 2011 Audi A3. The worst part was having to remove the steering wheel to get the ignition plug out. I paired this with a drone mobile module and absolutely love the pair together. I would buy this 100x over again
