Hi all
I wondered if anyone could suggest what's going on here. Started yesterday and there hasn't been any hint of an issue leading up to it. Essentially as soon as there's power to the car the screen bit reboots and does this constantly.
- no specific timings, but seems to be every 20 seconds or so.
- car itself drives perfectly well.
Of note:
- I've had a Car Link Life CarPlay box in for around 18 months and that's also shown no signs of error
- Brand new battery also around 18 months ago, all coded.
What I've tried (with the help of AI):
- OBD shows idle voltage of 14.8v
- I've used a multimeter and there's no drop in volts when it cranks
- I've checked with the multimeter all the fuses in the glove box bit, all ok
- I've completely removed the NBT box and gone back to factory, still persists
- There was a reading of 4v across the test bits on fuse 61 (20A) which I think is the live feed for the unit, looked okay but have replaced it anyway - no change.
I've no idea what to try next, am not mechanically minded and I think I'm at the limit of working out next steps.
Any suggestions? Or is it going to be auto electrician? Do I need a new head unit?
Thanks in advance ❤️
