I have an 2017 Montero sport. having electrical problems.

Does any had similar issues:

1st issue was wiper washer has low water warning, even it is full. This was going on for the past 3 months during our last PMS,
2nd issue came 3 months after: The car stereo memory is lost after engine off. That means all radio station, even Bluetooth pairing are all lost.
Also there is no GPS lock so when you run the engine it states "application error"

And another hazard is when GPS program hangs up, the rear camera image will freeze.. not recommented to backup while the headunit reboots for 2 - 3 minutes

If any one had the same issue.. can you let me know which fuse number? driver side or engine side?

I cant wait for the next PMS and want to repair this in case. Thank you.
