Hello to you all, I bought a tomtom go 720 with navcore 9.430 I installed a map 885 and work very well except the bluetooth which after a very brief research (not even one second) tells me that found no phones, with a red screen, I tried with all available navcores in tomtom home but still the same problem, that's two days that I try without success, Help pleas and thank you in advance.
