Apparently, it's a hardware limitation that does not allow Telenav to transit turn by turn directions via Bluetooth headsets. I seriously need this feature as I ride my motorcycle to my clients. The following devices allow communications via bluetooth for phones that don't have bluetooth via a separate 'black box' unit. With this in mind, i wonder if this will bypass the hardware limitations on both Nextel blackberry models to allow Telenav's turn by turn direction via bluetooth??? Can someone more technically inclined verify if this is a possibility?
