I was on the fence with upgrading the Commanders tech and finally pulled the trigger when BB emailed me a customer appreciation sale coupon. That made the decision easier and I'm happy with the install so far. I replaced my RER head unit with a Pioneer DMH-WT7600NEX. I won't go into much detail other than I needed the Bluetooth, wireless Apple Carplay, and the ability to play music and movies by USB with a video out option. The deck gives you some options on positioning, where you can have it flush to the panel - did this but due to the flatness of the Commander I was unable to install the back plastic cover over the mounting screws - also very little in the way of tilting the screen, so I reinstalled it sticking an inch out of the deck. I've positioned the panel center but you can move it an inch or so right, or mount it left.
To make it possible, I installed the deck to a Metra 99-6511BB - I consider this deck fairly sturdy. During install however, I was able to slide the deck forward out of the case. I added some pressure to the plastic tabs by wedging rubber stick pads between the deck and the installation kit - problem solved.
I am able to retain my stock steering wheel controls by way of the PAC RP4-CH11. They provide you two harnesses, so I had to begin by checking my stock plugs to see which one fit. One is square, the other is somewhat rounded on top - mine was the later. Wiring the Pioneer harness with the PAC was fairly straightforward with the instructions provided. I'm no electrician outside of guitar pickups, so I went with the heat-shrink / wind-proof lighter combo.
I purchased the Maestro AV-CH1 for rear view camera and video connections. These connections were pretty straightforward with the factory Pioneer harness. However, I'm having difficulty connecting the rear VES. It could be a connection issue, a setting issue in the Pioneer or something else - I have some research to do but imagine it's possible. I have decided to purchase parking brake bypass so video on the head-unit can be viewed while driving. The Pioneer provides parking assist lines and they are adjustable which I need to do still. I am considering an upgraded (higher-definition) rear view camera. Most likely get a junk handle and work on fitting a Pioneer camera down the road.
A Metra 40-EU10 antenna cable adapter is required.
Optional that I know of, Sirius XM cable and stock GPS cable converter. I mounted the new Pioneer GPS antenna next to the stock antenna under the dash.
I routed the included mini USB cable up through the hole in the glove box where I have a 128GB usb drive.
It's nice being able to look at my phone and be told where I parked my car. I've only had the unit for a few days and still learning. Cheers!
