The Kenwood KMR D558BT that I have fitted to my Crossfire worked fine till today. I received a phone call via bluetooth this morning with no problem but now for some reason the bluetooth symbol on the radio wont come on now and when I search with the phone it says it is switched off or out of range. I think that the phone is now pairing to the radio but not locking in for some reason, hence the radio is not recognising the phone. Any ideas please.
