The install in our new Camry was straightforward enough, especially with all the info available on Bulldog's website. I elected to solder connections to make them more secure, though. The trouble is that it quits working from time to time (and it's not working now!), and so far it's been a grounding problem. I followed the directions for grounding explicitly, but this time I think I'll go for the fuse block or a soldered connection to an existing ground wire. I'll revise this review if it turns out to be something besides a grounding problem.Those troubles aside, the system has worked flawlessy. Range has not been the problem that other reviewers seemed to have trouble with.
