Instead of posting this in my AR2 - iP6 - iOS8 thread, I thought I'd start a new thread for visibility.
If you have an iPhone 6 and have noticed any bluetooth issues with your car (or aftermarket head unit?), then apparently it is a known issue.
I read about it here. Here's a quote from one of the posters.
"... it looks like there is an issue with the iPhone 6.
I was just on the phone with an Apple iPhone Tech support guy who just talked to one senior support guy. He just told me that there is a compatibility issue between the bluetooth used on the iPhone 6 and some car navigation/bluetooth. He told me that the issue is coming from Apple. And a solution maybe be provided at a later time in a patch."
It's wait and see time...
