mazda cx5 not answering calls

iphone5 not answering calls thru bluetooth.

reset network settings-no good.

changed settings general, accessability, physical&motor from default to headset-no good.

deleted mazda from bluetooth and made new pairing-no good.

called apple they want me to backup and restore as new phone?

called Mazda and found the Iphone5 is not a compatable device, yet.

very frustating.
