Got my car back yesterday evening after the MD completed the updates.
Everything is now working perfectly and Apple Carplay is brilliant. Very smooth and quick to use and works especially well with Waze and Spotify. I love the ease of messaging and using Whatsapp too.
Some people don't like the interface (the dealer warned me about it!), but although it is a bit "Child-like" it is very clear.
Interestingly, the updates they have applied are noted as "recalls" on their paperwork so seems odd that JLR don't notify owners? I would have thought it would have made sense for them to do so, if only to avoid people having to complain!!
The recalls are : N186, N196 and N222 V2. I presume some are covered by the 18C update talked about on here?
