Poor documentation, but a good value and works wellI would like to give this 5 stars, because the product works but the documentation is not good.I spent quite a few hours getting this working. The documentation is correct for the wiring portion, but the programming documentation is bad so you don't know what to expect or what to do if something goes wrong.I disconnected the CAN-OUT and KEY cables on my head unit. No reason just didn't know why they were connected (see previous statement re-documentation). If you do that then the remote receiver won't work when wired up.Also why do I have to solder and sleeve to get this working properly? Can't we get a plug for the receiver? I think that is worth knocking off a star on its own.Another nit is that it is very laggy.5
