I'm afraid I don't agree with this at all,My second generation Roadster used to have exactly the same symptoms, so you'll be disappointed to know it was a phone, not car, problem. Reinstalling the phone software always cured it for several months but then it would happen again, initially when the phone battery was low. It's never happened since I got a new phone which does rather suggest the car is OK.
I've only ever connected via Bluetooth and I concluded that the Mini must require a rather good quality Bluetooth connection.
Just to add - I and at least one other are experiencing problems with iphone 6's, Now i'm sure plenty of people will have negative views on apple products and please spare us all the remarks, but my point is, these are NEW phones and not obscure mank, out of date bricks that we are experiencing problems with.I'm afraid I don't agree with this at all,
When my Bluetooth stops working, it stops working for everything, you cant add another phone or any other device, so the problem is definitely not down to a single device, otherwise I could simply add another.
Also, when it stops working so does access to the electronic manuals in the settings menu.
I'd prefer the wired connection but, and I'd be really happy if someone can correct me, I don't think the phone button works without the BluetoothThese kinds of issues are why I avoid Bluetooth for this kind of connection. As with all networking connections (telephones, computer networks, peripherals), a wired connection is generally more stable than a wireless one.
On my MINI I've gone in to Bluetooth config and turned off everything except Telephone 1. I'm limiting Bluetooth to features that absolutely require it. Otherwise I'm preferring USB. The hassles outweigh the potential convenience.
I won a 2010 Mini Cooper S that I love but I too have started to experience the same issue. One way I noticed it is not the my phone (Balckberry Classic) the Bluetooth menu in the mini no longer lists the 2 phones that I have paired to the mini system. Then when it does work the the phones appear and I can delete the, or change the priority etc.My problem is as follows:
Once a week the Bluetooth subsystem will fail. I have radio visual boost. All Bluetooth menu functions lead down to the same "Please Wait" window.
Stopping the car, even by getting out & full lock and back in does not solve the issue. Only leaving the car parked for around 1h does the job. Very annoying.
Car dealer does not want to acknowledge. Saying is a problem with my phone (which obviously is not) . Very annoying * 2.
