Yes, it can not be activated in the menu, if I try to enable a few seconds after writing "can not initialize the bluetooth connection." In the test they do, I activated only in a situation when after downloading an update insignificant (help text) from the site myGarmin, the zumo me the bluetooth enabled but when I try to go once the pairing error, and as the name of unit is a series of characters, and if I try to change the name makes me change, but if I go out and return to the menu, I find again the same characters ($ :/> L). If I power down and power back up, the BT is no longer active and again becomes impossible to activate.
I've try to make a downgrade and upgrade of fw, but no success. Thanks for anyone help.
