I have the most annoying connection issues with my Bluetooth and it also happened in my old Octavia.

Everything appears to be paired, but you get no sound? No sound from calls or streaming music.

I've tried repairing my phone but it still happens.

Can safely say it happens at least once per day and takes ages to get it reconnected, but then it just connects when your least expecting it.

I have an iPhone 6 with latest software and my car is a 2012 Superb Elegance.

Any ideas?

If it has done it with different car the common denominator is the phone.

I run an iPhone6 in all my cars(3) and it is pretty seamless, never had issues.

Try and get hold of a different phone and try it out but as said it must be a glitch in your Iphone6.
