Hey Wes,
Bought basically same system from AliExpress as well and once I finally figured out install (lots of bruised knuckles and patience needed!), I am super happy with CarPay like you. I do have a couple of issues I haven't figured out yet, and wonder if you've experienced same:
• Power to factory audio shuts off after 20 minutes regularly, so I have to turn it on again to power Android. It's got me stymied because one of the two purple wires in the Android wiring harness doesn't have anywhere to plug in, and CAN A, CAN B aren't identified. I haven't been able to get any instructions either
• I haven't figured out how to switch displays either, not seeing NBT EVO ID5 as an option.
I really appreciate any insights you may have since you've installed basically the same system.
