Infotainment system fault

[Aidy80]

Hi guys! Just joined the club and I’m enjoying it so far. Keep up the good work!

I have worked in a mechanic in a Toyota dealership this past 10 years so I’m good for info. Don’t be afraid to ask anything.

The day after I left my job in Toyota my radio and nav wouldn’t work. The display looks like it’s booting up then the screen goes blank.
Has anyone experienced a malfunction in their infotainment system like this?

I plugged in my dodgy version of TechStream and can’t access the system  I pulled a fault from the instrument cluster B150A Lost Communication with HMI-LAN. All fuses and connectors are sound. Any info would be gratefully appreciated.

Welcome!

No idea but a quick Google gives some troubleshooting procedures for another car, but a Toyota still.

Hi Guys! I'm still stuck with no Infotainment. I've been reading about a botched Lexus/Toyota wireless update. Are there any downloads so i won't have to make the 200 mile round journey to get rode by a Lexus dealer 😅
