Crux AVITY-01 installation question

Hi All,

I've been hitting a couple issues with my avity install... wondering if this is common or if i got a defective unit? It seems that the parking break override periodically disconnects while driving. I can get this to happen every time if i hold the volume down button for a few seconds. This disconnects me and i have to re-hold the up arrow for 5 secs to re-engage. I have the 5 button SW (white wire) connected, and i'm in a 2016 tundra.

Other than that it works ok, but this is quite annoying! I'm thinking about jumping back in and adding the manual override switch instead of using the 5 button... but perhaps my model is just defective?

I also notice the sound is quite low, and the screen has a border from the top, left, and right by about .5" even with stretch view selected in the AV window. Sorta annoying as well. Any of you also experience this?

Will probably just roll with it as-is as running the AV cables through the dash was a huge pain. Don't want to do that again...
