I don't think they are related. Once the battery discharging warning light problem is resolved, we can continue troubleshooting.

[QUOTE=rkw77080;10756720]The next step is to hunt for bad fuses. I did a search on the repair manual to identify all fuses that are related to the navigation display and circled them in red on the diagram below. Please note that the fuse box location is identified with a number (see legend on lower right corner of the page). Check to make sure all these fuses are in good working order.
okie dokie I will check them in fact I may just replace them good or bad, Thanks again for the support

Hello I've checked changed all relevant fuses and I still dnt have any power yet. I still haven't replaced the aftermarket amplifier fuse yet had to order it because it was in stock locally.

Fuse 33 on passenger side
I had the same issue. I was changing my battery in the dark and mixed up the positive n negative on the new battery. There was a big spark then I realized I had plugged the wrong terminals . I checked my fuses and saw that my 140 amp fuse was blown so I got a new one from Amazon . I don’t havethe after market amp issue but the Navi/climate Radio etc was completely dead. I found out it was the 7.5 amp fuse box on the passenger side kick panel under the glove box. It’s hard to crawl in there and see and then to take it out.If you look at the owners manual it’s fuse number 33 it’s a tiny 7.5 amp fuse. I didn’t have on so I took it from the spare in the fuse box by the battery under the hood.Now everything works fine. My radio my smart key however I have a VSC Traction Control off Check engine light. I’m gonna use a code reader tomorrow to see what it is. Changing the 140 amp fuse was a PITA. I broke one clip and almost lost the back 8mm screw. Did u get a CEL? What was it for and how did u correct it?

Solution
Ok code reader said P2118. Looked it up on Google, it was the ETCS fuse. Which means your car idles at 1k rpm and when u hit the gas nothing happens. So I changed the ETCS fuse and now everything works great. So moral of the story is don’t change the battery at night n make sure u plug cables right. One interesting thing is that this whole time I unplugged the battery completely for almost a day and when I put in the new one. All my settings were there.
