IMO, the difficult or tricky parts of the job are:I know my limitations. Pulling apart the dash and installing equipment like this is way behind my abilities.
1) Knowing what order things need to be taken apart on the dash to get access to unbolting the infotainment display.
2) Routing the cabling for the microphone - I'm not sure I'd be comfortable routing it up to the rear view mirror like Eric has done on his installs.
3) Routing the cable for and installing the USB port that's needed. If the USB mount that comes with the Naviplus was the type that has a nut on the backside like add-on 12V sockets (and many of the add-on USB charging ports) have, it would be a simple matter of drilling a hole of the correct size and mounting it, but it sounds like it's just a friction fit sort of mount. Eric said he made use of the existing USB port that's used for connecting a flash drive or phone to the factory infotainment system, but I'd like to avoid modification of the stock wiring as much as possible.
4) Similarly, with the other system that's available from EC Vision & Sound, routing the GPS antenna cable to a suitable location to mount the antenna.
Connecting the Naviplus to the factory wiring harness sounds really simple once you know which connectors need to be used.
Having access to the factory service manual should make item 1 much less of a concern. Where do people download and/or purchase the FSM from? In my case, I suspect 2018 or newer would work as that's when the latest dashboard refresh was and changes are pretty minimal for 2020.
I'm not sure how to get past my other concerns, but I'm very tempted to go with one of these options.
