I picked up a 26 V6 manual back on fathers day. It had sit on the dealer lot for 6 months and while doing my around the car inspection it gave me the low battery warning while on accessory mode. When I started the car to leave I got a yellow triangle and a message that some of the various ADAS didn't work. I joked with the salesman that I already got my first triangle and drove home. It was actually a great drive home. No issues with the car and my android auto worked great. When I restarted the car the next time the triangle was gone and all the nannies were in full force. I've driven it twice since then with no issues. I have read on other posts about the volume thing. I haven't really played with the radio much yet but I assume I will have that as well since that seems to be software related.
In my quest to try and de-nanny the car I came across the safety module in the wiring diagrams. Its fuse 14. I was going to pull it to test exactly how many errors I would get but havent gotten around to it yet. It seems to be a dedicated fuse only to that module and does not run the camera or other sensors that I can see.
