Hey - couldn’t find a good solution for this online. My Gs350 started to have the navigation screen flicker as of late. I tried to reboot and will be taking into the dealer for diagnostics. Was wondering if anyone has gotten a clear resolution for this.

Never seen this problem on a GS before - although the same system is used in various vehicles from the '13 GS, '14 IS, '15 RX i believe. I would check the lexus driver site if there is a firmware/software update. The dealer might go this route first while performing diagnostics.

However, if my instincts are correct, you may need a new navigation/unit - the vid you posted makes it seem like the display driver is going bad. The dealer will likely want an arm/leg for it, so if you do need a new navigation unit, look for one on eBay where used ones go for around $500.

Does it happen all the time or does it only happen on startup/if you perform some action?

I seem this issue one 2017 GS350 F Sport for sale in my area when I searched the Lexus VIN report on it. The dealer didn't fix it for the person so that person decided to sell the car.

Here's some guesses which may be a long shot.

How old is the car battery, can you get it tested?

Check the fuse if lose?

hey - thanks for this information. It typically happens after like 15 min of driving I've noticed. Sometimes it happens after starting up the car, but rarely. I use to think it was getting nudged by the USB charger for some reason.

when you say navigation unit are you saying the screen/display or the radio multimedia drive?

thanks!

it's not really that difficult to pop out the navigation screen and/or the radio just requires 10mm socket, a plastic trim tool and a phillips head screw driver. Maybe something got loose with one of the plugs back there?

Get the car scanned with techstream. You'd be surprised how many error codes the radio can store.

@WindyRx350 I meant the radio unit itself which houses the components for both radio/nav...like this: https://www.ebay.com/itm/13-15-Lexus...M/113478732103

The screen itself is just glass and it doesn't look like the screen is buggy. Here's a helpful thread if you need to go the route of changing your radio/nav unit: https://www.clublexus.com/forums/gs-...out-there.html

@WindyRx350 Did you ever fix the issue? Did replacing the head unit/HDD fix the issue?
