Well that kinda depends on how good your electrical skills are and how confident you are in them. If you have none I would say bring it to some type of either audio installer or tbh I’ve even had decent luck at both the local P.C Richards and Best Buy with installing that type of thing.
Trollz3457, Thanks for your reply. I’m confident with electronics, I have installed several touch screen radios with backup cameras. I find radios are pretty straightforward to install. Red wire(12V), yellow usually(12v constant), ground, signal and speaker wires. A test light with common sense really helps. But remonte starters, I guess I just have to go with trial and error but I do not think that It would be a good idea since I might damage a fuse in a module and make a disaster but I would like to learn how to install one on my mazda. It’s a tough dilemma..
Personally I haven't done one on a 2nd gen but I've done it on multiple 3rd gens and the only really confusing part would be finding out where to tap the remote start system into the starting system. It may be easier since the computer systems aren't as touchy but I would try just finding an install video on youtube before attempting anything.
Absolutely, more research and studying needed
