Long winded post but here goes. I had a 1200 gsa. Moved the bmw satnav mount to the left which left enough room for a cheepo phone mount to put my iPhone 7+ bescide it. Happy with setup. Of course I’m never REALLY happy and after over 2 years and 60,000 km of ownership traded for a RT. So trying to set up my phone I find that it won’t fit neatly on top of the bmw satnav cover. A iPhone 5 would. I can get my hands on one but can I yolk it up to my phone by Bluetooth so it can down load maps as I ride along. I don’t want another sim/contract. Or am I going down a dead end and end up spending more on what I want than I would if I just bought a second hand nav5. I got a tomtom on here recently and it works great but I find it much handier to google whare I want to go then just press directions. Obviously not available on a old tomtom. JJH
