Nothing to do, same problem with phonebook, initializes, it connects, but when switching the network to the vehicle will lock the LG bt. It also blocks the network of the LG and I have to reboot the device.
LG G2 support rsap, in fact it connects to the vehicle and one of the many tests I've done have also able to make a phone call, but there will be some problems with some of the file bt when upgrading to KK that breaks the connection after a few seconds, someone in the forum thinks it's a file to rename. bak, but I do not know which one.
Any other ideas?
