How to Synchronise IPhone 8 Telephone Directory with Columbus Nav Unit

Hi,

Just in case someone has a similar fault. I've just upgraded from an Iphone 6 to Iphone 8 both running IOS version 12.3.1.

New Iphone 8 paired AOK with 2014 Skoda Superb II Elegance Columbus Sat-Nav via maxi-dot, however new phone book failed to synchronise with Columbus unit,reported no entries (however there were 200 entries in phone book).

Tried several different options still no phone book reported as available.

Noticed old Iphone8 definition is very similar to old Iphone6 definition I.e. New phone name= Iphone8XXX Old Iphone
