Navtool navigation issue
hello,
i just did the navtool install. Everything was fine during the test runs. But when I put everything together, the navigation screen does not open upon starting the key. I can see from underneath that the screen itself briefly turns on with the Lexus logo but then it turns off. When I leave the battery disconnected for a long period, the navigation opens upon opening the keys but then it turns off, this time I can press the map/voice to bring it back up, when I turn off it turns off normally but next start, won’t open again. I can’t press the map/voice button to make it open. Any help would be appreciated.
thanks in advance

Your auto function is disabled. May be the wire came loosen. Try to reseat the connector.

Unfortunately I dont think thats it. I cant use any buttons to turn it on. nothing works. It might be a loose wire like you said but nothing looks particularly loose.
I happened to have another nav screen assembly, that one does the same thing/doesnt work too. All fuse/relays seem fine but ill try to swap out some relays tomorrow and see what happens.
Something is preventing the navigation from working and I cant figure out what it is. I should also mention that for some reason the car's battery was dead (maybe a door was left open) and it did not have power for a good few days at least. Not sure if this is relevant at all.
Soo lost on this to be honest. so frustrating. I think ill disconnect the navtool and see what happens as a last resort.

Sooo I disconnected everything one by one and checked. as crazy as it may sound, it was the vais tech SL3U-L that was in no way connected to the navigation screen was causing the issue. the vais tech was really hot to the touch and once I disconnected it from the stereo, everything worked! so this is prob a defective unit, the company said their units are defective 1/10000 and I do believe them. This just happened to be that one time.
If youre having issues and have installed a vais tech recently, check that!!!!

Good to hear. I don’t have the vais tech, but will keep in mind.
