I just upgraded my JVC "KD-X330BTS" unit firmware from ver.0106 to ver.0123, the process completed and the unit rebooted successfully.
Unfortunately, after that Bluetooth feature didn't work, either in "source" button or by "settings", all the time keep giving me "PLEASE WAIT" then "H/W ERROR" on the screen, other features work fine, although the unit became very slow in tuning.
try to reset the unit and repeat the whole process again and again, but nothing changes.
