I recently updated my 2016 8.4 to the DWT-7600NEX too. Here are some pics. Works great. Sound is much improved. Retained all the factory functions. Now get wireless AA and can turn on netflix, etc. for the family on long rides using a chromecast plugged into the hdmi port.
Detailed list of items required for installation.
DWT-7600NEX
MAESTRO RR OR RR2
HRN-RR-CH3 T-HARNESS
NAV2 HARNESS ( TO USE FACTORY NAV ANTENNA )
SAT1 HARNESS ( TO USE FACTORY XM ANTENNA )
XM SXV300V1 TUNER
EURO ANTENNA ADAPTER OEM F TO MOTOROLA M ( FOR HD RADIO )
SCOSCHE CR1297DDB DASH KIT
AMERICAN INTERNATIONAL UPT900 DIN POCKET
The only grumble I have about the install is the scosche dash kit. I wanted to retain the factory buttons for the HVAC. The screen still shows the HVAC stuff as well so you can use either BUT there are two things to note.
#1 - The dash kit indicates it's for single or double din installs and was to include a single din pocket to fill the void when installing a single din unit such as this. It does not come with it. Had to do the install and then pull everything back out days later after I received part #American International UPT900 ( din pocket ). Now everything looks great. Even have a hidden cubby behind the screen for small items I don't care to have seen, w/e that may end up being...
#2 - You have to disassemble the hvac controls including removing the knobs. Kinda a PITA but with a little patience it can be done. 1st one coming off was the hardest.
