HO-K. That is a Sahweet earth.
Hrm.
Because I'm not super mechanically inclined that took WAYYYYYYYY too long. About 10 hours in total I estimate which is tough since I did this same thing to another 1992 a few years ago.
THIS IS THE UNIT I WENT WITH.
But I did it.
The shallow head unit required ZERO cutting of either the trim or the back of the dash when installed. It took FOREVER for me to get it lined up correctly in the opening. At one point I even pulled the head unit back out and pulled the mounts off to start over because it just wasn't working for me. It's slightly crooked now, but it works beautifully. The Metra Bose wiring harness is long AF, but it's coiled up under the glovebox now and here we are.
Things to note.
Wireless Carplay = Awesome.
Connection for a phone on the back is USB-C. Not USB-A as so many are. It comes with a USB-C Extension which is easy to run into the armrest which is mostly just for charging my phone now. This unit CAN have two phones connected at once; which will make my wife happy since she's usually the DJ on car trips.
The unit requires you plug a GPS antenna into the head unit to use Carplay GPS. Not sure why, I can only hope it uses the GPS antenna to assist the one in your phone, but I have no idea. I ran this into the glovebox easily enough.
Personally I don't like the 4 touch sensitive buttons on the left side. I don't always hit them the first time causing a delay in whatever it is I want to do but for the volume it pops up a menu allowing you to use the screen to control the volume. It also has clearly defined volumes on the screen for BOTH Music, and navigation announcements, which is really great.
Radios/Cars are SUPER complex compared to years prior. There must be 20 different wires that I taped off because I didn't need them. Speed sensors, reverse sensors, camera sensors, parking sensors etc etc. I worked on this for a couple hours yesterday afternoon and stopped so I could read about the different sensors to know if I would cause myself any heartburn not connecting them.
There are 3 different ground wires in the harness to from the radio. ALL must be connected in order for it to operate.
I did NOT hook up the antenna for standard Radio partly because after hunting for it for about an hour and just being unable to find it I decided to move on. And because I usually listen to satellite radio so I'm not sure I'll need it. We'll see if I regret this or not.
If i run into any major issues with his head in the next couple weeks I'll be sure to update this post, but otherwise for the money I'm pleased. Hope this helps anybody looking at a new head unit but not wanting to modify the trim or inside of the dash!
