Hey..New to the forum.
I have a 2018 Lexus GS 350 F-SPORT.

Today i changed my battery at autozone.. Did not disconnect anything else but the battery.. After the change i noticed my backup camera is not working..
Also i have an aftermarket front camera from Beat Sonic thats also not working when i press the button.

Does it take time for the car to be off in order for the software for the camera to load up?
Is there somerhing i should be doing to remedy this?

Note i never had an issue with both cams and this was my first battery change on the car.

Have you tried disconnecting the battery again. And reconnecting, then pressing the start button (without pressing brake so engine doesn't start) and just letting it sit for a min or two, to let systems come up. Then starting the car?

No... my infotainment screen still works fine radio and gps...whenever i go into reverse OR press the aftermarket front camera button from Beat Sonic the screen still stays on to whatever i had it on...Just the camera is not comin up.

Do you have Beat Sonic installed? That's where I would look for this problem 1st.

At what point do we recommend everyone uses an OBD memory saver when changing the 12v battery?

I do for the front cam only..the rear is stock.
never had an issue with the Beat Sonic front cam..worls seamlessly with the infotainment system prior to this

Yea my fault on that..

The Beat Sonic system is causing the issue. There's a special procedure to reset it when the battery is disconnected. This affects both cameras since the rear camera plugs into the splitter for the front camera selector system.You can find the process on their website/instruction manual

Maybe too late but thought I share. You should check the fuse for the camera system/navigation system. I installed an LED bulb for the license plate light and it shorted out the rear camera after a couple of months of use. Replacing the fuse and the light holder fixed the problem. System restarted and restored.
