Losing Bluetooth for no apparent reason...?

[Huxsta]

We've owned the car for over a year and have had no problems with my iPhone 5s and my wife's Samsung j5 connecting when either of us jump in the car......up to now! Now every time we start the car the Bluetooth list of our phones has disappeared and we have to input them again in order to be hands free..... The car hasn't seen any garage for updates etc and neither phone has had any known updates carried out over the last 3 weeks of this new issue. Any ideas people?

Mine has been doing this randomly ever since new.  No idea why, and very annoying!  I put it down to the CIC or Combox failing to boot properly or resetting itself.  Whatever it is, it is completely random and only by using a cable for the music streaming does it seem to stop happening.

It may be worth checking your Battery condition.

It could be a battery related issue as you say, after all I'm guessing it's maybe still on the original battery? It starts absolutely fine but I will get it tested when I get some spare time and go from there.
