I have a MY19 with intouch control pro. The annoying issue is that with stop start enabled the infotainment and central dash display cut out for a second when the start process happens. This also cuts the USB for CarPlay making it pretty unusable. Not sure if this is an electrical problem or a software problem. Anyone seen the same?

I always disable stop/start straight after firing the car up, so never seen this issue, sorry.

I use carplay and on the odd occasion when I’ve forgotten to switch off the stop/start it hasn’t affected the infotainment at all so you do have an issue, it may be a slightly weak battery so the voltage drops too far during startup?

I’ve recently seen a similar effect where my screen briefly goes blank when the engine restarts. I’ve not noticed any audio impact and assume that is because I’ve not had anything playing at the time. I tend to agree with GusA an that this could be another consequence of a low battery.

If the issue were a low battery then I’m sure stop start would not activate as it checks voltage.

I'd guess the actual start draws so much current for a brief time that there's not much left for anything else. Another reason to disable it as a matter of course - it serves no useful purpose. ;)

Update. Car went into JLR Main dealer. They diagnosed a power control module via an error code. The power control module was replaced (6 hours labour required) and it has resolved the problem. It appears to have resolved an intermittent usb connection problem too which appeared related.

Just digging out an old thread as I am having this same issue on rare occasion when the engine starts on a stop/start at an intersection the infotainment system goes black, if I have carplay on it loses connection. Looks like there is a solution but will need to take to a dealer. It isn't often and so will wait for service but good to know it isn't just me.

Had the same problem with screen going blank when stop/start kicked in. Just been to the dealers and they have updated the Body Control Module? Said that the software was way out of date.
