I installed this on my 05 Tahoe and I will say that it was pretty straight forward. The instructions were not bad. Youtube is always helpful *hint*hint. Install took me about an hour, but that was mainly due to two wires (yellow and white) being too faded to tell them apart. So I'd say without that small issue, I could have knocked this out in 25 mins or so. They do have a customer support line, but it's a call back system and they took about an hour to call me back, by then I had Youtube'd what I needed. That's the only reason I gave this 4 stars. I can start my truck from about a half of a city block away unobstructed. Just be aware that most vehicles will not need everything that comes with the kit. You will not need really any mechanical skills to install this,you just need a basic mechanics tool set like one from Harbor Freight, and be a bit flexible because you will need to get under the steering wheel area. Overall I am extremely satisfied with this unit and have installed 3 in my friends vehicles without any problems. I hope this was helpful.
