I have jumped my 2016, and changed the battery, and all of my systems still work. If jumping the battery and changing the battery outside of the dealer network caused the screen/infotainment system to quit, half the RX’s on the road would be without displays. I can just imagine the highlighted warning in the owners manual - DO NOT CHANGE THE BATTERY UNLESS YOU ARE AT A LEXUS DEALERSHIP. Something else is going on here.
I don't know if it's a matter of keeping the settings or something else, but the new CTek chargers have a button that will keep the electronics supplied with power if you change the battery yourself, mine doesn't have it, too old I guess. Don't you love technology!?

Yes i agree, but I used an independent Toyota/Lexus garage. Any electronic repair I would always have the Lexus dealer handle, because we are talking nickles and dimes savings vs big issues if they screw up. Hybrids take repairs to a new level that I don;t want to risk.

Blank screen
My battery died & I changed it, and suddenly the Navigation screen does not work. When you start the car, the Lexus logo shows up normally on the screen and the back up camera works. However, the navigation, bluetooth, radio, etc do not work at all. The screen is just black. It all worked perfectly prior to the battery change.
I brought it in to 2 different Lexus dealers and they both said I need a new screen because the battery change may have "shorted" the navigation system. I am an engineer and this makes no sense to me. I really think it is a computer issue, but I can't get it to work. I have checked all the fuses and tried unplugging the battery & restarting the car several times. This absolutely ridiculous in my opinion, and enough reason that I would NEVER buy another Lexus again. They have absolutely no customer service since my warranty just expired.
I have looked this up here & other websites online. I have tried all the suggested fixes to no avail.
Anyone with any suggestions? Do you really think the navigation is "shorted" as they say?

I assume you reset the system by holding the power off button on the radio until it shows the reset process. Sometimes I have to rest the system because it does not recognize something in the USB slot or the screen just goes blank.

The battery is original and 5+ years old, maybe time for replacement. Tried different reset options, none worked, tried with vehicle running and held radio power button for 20 seconds, tried disconnecting battery for 1 hour, then reconnected and press start button without putting brake on , accessory mode, then held power radio button, nothing. When starting Lexus logo comes up for a few seconds then blank, also backup camera displays fine.
