I'm new to car audio tech but wanted to get CarPlay in an older van that I have, so I installed a DMH-WT8600NEX unit with a Crutchfield wiring harness and am having a few issues:
The biggest issue is that the screen flickers every 4 or 5 seconds, but the audio doesn't cut out. This feels like it could be a hardware issue, like a bad panel. The flickering does not seem to be connected to any movement/jostling of the unit, and I've checked the connector of the screen to the unit itself, everything seems right.
The other thing, which might be a firmware issue or oversight, is that I can't seem to get the CarPlay screen to dim at night. The screen outside of CarPlay (the NEX stock screen) does seem to dim, though it's unclear if it's timer based or is picking up the illumination wire. But either way, I can't figure out any to get a different brightness in CarPlay itself, making those midnight rides of mine a bit less enchanting.
Any thoughts? I'm thinking of following up with Crutchfield about the first issue but wanted to know if I should try anything in particular before I do
