There is a conflict with the bike and Garmin's new Zumo 660 firmware update 5.0. I downloaded the update and the voice directions cutout and there is no cellphone sound as well. Garmin gave me an exchange and the new one had firmware 4.90. The audible directions worked as well as the cellphone sound. When I downloaded the 2015 maps, it automatically updated the firmware to 5.0 and it quit working on the new Zumo. Garmin said they just became aware of the problem and working on it. In the meantime, I do not have any audible directions or cellphone sounds. There is no timetable for when it will be fixed. The GPS does have sound outside of the cradle. The device cannot be reloaded with 4.90 once the 5.0 is installed, you are just SOL until Garmin can figure how to fix it.
