i am having trouble with when i ring from my tomtom i can hear the ringtone of my landline,when i turn off my tomtom and turn it back on ithen cannot hear it if i disable then enable bluetooth i can hear it again,on contacting tomtom support i was told to reset my handsfree which entailed deleting loose files and a bin folder and phone_databse folder then updating and resetting of tomtom ,if i now go into my tomtom and look at folders there is now no phone_database folder,Is this normal or do i need this pone database folder,ihave done a backup so all the files i had before the resetting and deleting i still have.
