Bluetooth Does not connect with modern iPhones.
After a lot of research, I decided to step and go for TomTom Go Discover 7" rather than a Garmin set up. WHAT A MISTAKE! Sorry guys but judging by the hundreds of queries and comments on this theme (bluetooth won't connect with iPhone 11) its high time your technicians should have resolved this without any flickering or messing around. This forum isn't the easiest to use either!
This snag has been around for years and yet no clear responses from the top. I am so sad because my new kit was a gift from my wife. Sorry if no SOLID resolution by the time I awake tomorrow, the kit goes back for a full refund and real social media moan.
