Shorted DOME with aftermarket head unit...

Hey all,

First off, do not buy a KUNFINE head unit off Amazon. That was mistake number 1.

I bought this thinking it would be a nice drop in replacement for my stock head unit. It came with harnesses and everything to connect to the car cabling. Got it all hooked up and powered on the car to find the "check hybrid system" notification on, stereo off, and all the warning lights illuminated.

Disconnected all. Put the original head unit in, and same, except now stock head unit wouldn't power on. Diagnosed this back to the DOME 15A fuse which was blown, but changing this wouldn't let me drive still. Had to remove the lead from the 12v battery and reset the system.

Now, everything seems semi normal (at least I can drive it) but I can't shift out of park without pushing the button. Seems like it's locked or something. Also my mileage has tanked. (Possibly just low because it was reset?) And finally the stock head unit no longer shows the car info (mileage, how much power is recovered from the brakes, and the average speed) on that graph.

I'm worried something deeper is damaged due to whatever that dumb head unit shorted. Any ideas where to begin troubleshooting or checking? Anyone else had this issue?
