Radio and monitor dead?
I was out today and stopped at home to pick something up. I turned the monitor and radio off and turned the engine off. Ten minutes later I went out to do a few more errands and started the car. But the monitor stayed off. Radio off as well. I am now unable to turn on either.Anyone experience this?

Haven't figured out how to remove the back seat to get at the box yet but I'm starting to wonder if my problems are the result of a dying battery. In addition to the touch screen and radio being dead, I am getting TPMS warnings that cycle from one wheel to the next and then it goes off and then starts again. Rear left to front right to rear right, etc. I spoke with the dealership yesterday about the fuse and was told by one of their mechanics that it would not be a fuse. It would be one of the touch screen modules that had died. If one goes out, the entire touch screen goes off. He also mentioned that the modules are ridiculously expensive, from around $1000 to $4500! Might be worth checking the battery first?

If you suspect the battery (BTW, it is comon to have a wide range of gremlins for low battery) put a VOM across the battery. If it reads anything below 12.6VDC that would most likely be the problem.
As has been stated in many other posts, these cars do not like low voltage.

Yes that sounds like a battery could be suspect. If you don't have a battery maintainer, you should get one for future use. Even when you drive them daily, they can slowly drain.
If you have a charger, put it on the battery now.
You can have a auto parts store check the load for free. They will even swap them out for you if you want to trust them. The battery weighs a good 50 lbs.
If you buy a new battery, charge it before use. They drain just sitting on the shelf at the store.
To remove the center back of the seat, pull up on the seat hump to remove it first. Four pins, one in each corner hold it down. Force is straight up.
Once removed, grab the center section of the seat back and lift straight up about an inch or so. There are hooks on the back of it that slide down on a couple of horizontal bars. Life first then pull it out.
Neither requires the use of tools. Once out, you will see the fuses. Fuses are numbered and you want a pretty bright light to se them.
Resting rate of your battery (battery with car off) should be 12.5 volts. If it isn't, she's probably toast. If the load drops below 9.4 volts while cranking, it's definitely toast but as I said, auto parts stores have a tool to load test it for free.

So, I went to Sears this morning and had them install a new AGM batttery. I also had them test it prior to installing. Reading was 12.6. Half an hour later I get the car back and start it. The touch screen, radio, TPMS, etc are all fired up normally! The dealership wanted $175 to determine which module needed to be replaced. Instead, I spent $227 at Sears. We see it on this forum all the time. If you start having weird electrical gremlins, check the battery first! Every time I read of someone having mechanics replace electronic components and then have the problem not be fixed, I wonder how many should have tried a new battery before playing repair roulette?
