Let me paint a picture: I've been toying for a while with the idea of buying an aftermarket touchscreen radio for my 2005 Honda CR-V... until my battery died and I didn't have the code to reset the original radio. So here I am needing a new radio.After a bit of research on Amazon I came across this one. Cheap, good reviews, let's give it a try.My process was kinda rushed, so I had no idea what the installation was gonna be like, nor what other things like "trim kits" were or wiring harnesses.I bought the radio alongside the recommended antenna adapter for my CR-V. Well, turns out I didn't need the antenna adapter, take note if you have the same car.I then proceeded to buy some quick crimp connectors alongside with the crimper/wire cutter tool.Ok, a bit more elaborate than I thought.Now, I do think I am quite a bit more handy than the average, but this was a first for me too.I removed the original stereo and unplugged the 2 wiring harnesses going into it and the antenna cable.Turns out that one harness was not needed at all. Good, less work for me.The antenna cable was good for the new radio too.BUT the next set of wires that went into the radio was going to be quite a bit of work. This is when I would have loved to know that there are such things as wiring harness adapters. They basically connect the wires that went into your old stereo and arrange them so that they'll work on your new radio.Plug and play basically. Unfortunately I can't tell you what wire harness works for you as I didn't use one.What I did do was cut the existing wiring harness to free all the terminals. I then stripped them all and crimped the quick connectors in place. One by one.Then I surfed the web to find a wiring diagram. Great, found one!Too bad that quite a few wire colors were wrong/mixed up, and to make it worse, some of the wires on the car were basically identical.I crimped the wire terminals supplied with the stereo and then connected the wires together looking at the diagram online and the booklet that came with the new stereo.First try, no luck, turned on for 2 second and then turned off. But at least it turned on.Turns out that it would have been nice to have a better diagram with he right colors. I switched a couple of wires and bam, the radio turned on, but the music only came from 1 out of 4 speakers. Not too bad.Switched some other wires and shazam! Music from all the speakers.Ok, great, now let me close everything up. Yeah, uhm, so that's what trim kits are for. Turns out that without trim kits you'll see the edges of the radios that should be hidden. Not ideal. Bought a cheap trim by Metra that was supposed to fit. Aaand, it didn't.Had to hack it and cut the frame short to make it fit, put some take to hide the cut and that's how it remains now. Still not the best fit, but good enough for me not to loose my mind when looking at it.All in all the process took me about 3 days having to work for an hour at a time as I didn't really have the time. If you truly take a whole day or weekend off and dedicate it to this project, you'll most likely make it work. That is if you're average in handiness.I don't really have the time to mess with the backup camera, yet, once I have more time I'll try to get into it. But it should be a fairly easy process.The audio is pretty good and I'm happy with it. The radio doesn't work in you're in CarPlay mode, and that's a bit of a bummer. CarPlay only works if you plug the phone in with a cable.I'm happy with the purchase and the process. My car looks a lot smarter now that I have the touchscreen. The installation problems were not due to the stereo itself, but rather because of the poor wiring diagrams from my older car. Your wiring diagrams might be spot on and make the process so much smoother.I'd buy it again.
