Installation wasn't too bad; I used the optional 'T harness' to make the connections to the ignition switch. However, I have the same problem now that another user here reported: Every once in awhile the remote goes "out of range" (the antenna icon disappears) when I try to start the car. I could be standing right next to the car and it doesn't matter -- it thinks that it is out of range. I have to try several more times to try to get it to start. I have no confidence that this thing is going to work now if I'm not standing right next to the car to see if it really started. So, not much use as a remote starter. I'm calling Bulldog tomorrow; if they can't get this working right or send me a working replacement it is going to be ripped out of the car and sent back for a refund.

I bought this item for my 2004 Jeep and was worried because I have very little electrical experience and it seemed like a monster job. Since my car was a newer one, it need part 791, a Universal Bypass Module which I also purchased.
Upon opening the boxes I saw a DVD instructional video, instruction and use manuals; and bundles and bundles of different colored wires; which terrified me enough to leave the whole thing alone for about a month before I got the courage to mess with it.
So yesterday, I sat down with the DVD, wire diagram for my car from their website, manuals and a piece of paper. I labeled all of the ports on the module, and all the wire harnesses; not that bad. I watched the video and wrote down step by step wire by wire what to connect to what.
I went out, on a very cold day, I got started about 4:30 and by 6:00 I was more than half-way done with only 1 call to the excellent tech support who knew exactly what I wanted to know. The next day, I went out, and spent another 1.5 hours and with one minor glitch and one more call to tech support everything was done. System works great! I tested it a few times and it worked great.
Don't let it scare you, it is easier than it looks, be patient and follow the instructions. The warranty and tech support are excellent.

Received product in less than 3 days, it has everything that was advertised. I had this product installed the next week and it works great, only thing is that maybe 1 out of every 8 times the remote looses range even when very close to the car and I have to attempt to remote start it 2 or 3 times before it goes, but other than that, no problems.

Product works as adversited, I've had it for two years now, never had a problem. Instalation if a different beast: Due to the extensive amount of features, there are a lot of wires to be hooked up, all of which are outside plain view, so you will have to do some disaseembling of the interior of your car (a few plastic parts) and be able to identify which wires are the ones you need (ignition, crank, dome light, brake light, e-brake, ...). So if you're fine with that, you will enjoy the benefits of this product (just make sure you set plenty of time to install it). Some electronics knowledge makes things easier but is not required (as long as you follow the directions exactly).

I have had the unit for over 2 years now and it works great! I use it every day in the winter and often in the summer. It was tricky to install but I have a manual transmission so there were additional steps that I had to do to get it to work. It honestly took me 2 weeks before I got it all hooked up and figured out. The tech support is terrible and never were able to help me with any installation questions so you better be good with electronics and good at troubleshooting problems if you want to attempt to install this yourself. I saved $400 in installation costs by doing it myself and I learned about my cars electrical system while doing it so it was defenitly worth it. It has tons of features and has a long range which is the reason I got it.
