dropped my truck off for the REV 4 update today

its supposed to be a big update, I asked for the list and have not received it (maybe someone can get it from TOPIX)

Noticed for the 2017's the REV 4 update changes the screen to look like a 2018.....much nicer for the 2017's

Will update when I get it back tonight

hopefully it fixes my seat bolster inflation issue

Re: ICT REV 4

If you PM me your email address I will send you a PDF of the release notes. It does not appear that anything relating to seat bolsters is addressed.

This seems to be 99.9% bug fixed and very little new features other than new menu screens.

Looks like the Phase 4 update still has issues, so I will wait a bit longer before updating. Let us know if you get an over-the-air update and if that fixes the screen issues that you shared. Thanks

Re: ICT REV 4

given that software updates tend to brick entire systems, it would be the last thing I'd DIY in a Range Rover.
Heck, last year (MY17) there was a map update that could kill the entire navigation system and people ended up having to go to the dealership to get the functionality back.

is it just me who's afraid of this thing?

will do. Not sure what’s suppose to happen when you hit the update button. All I get are 4 little colored bricks spinning round and round.
