Wishful thinking on your part, I'm afraid, Danabw, despite your 642 posts... It doesn't work like that. In fact, according to Gina at Telenav, there is no way to redirect the audio from Telenav to an earphone or external speakers:
"External audio devices such as headsets are not supported for use with TeleNav GPS Navigator. We cannot offer assistance with these devices."
"These devices" being Blackberries.
End of story?
Only if we don't cajole Telenav into figuring out how to do it. This is the only program I've ever seen that cannot route its audio to the speaker, bluetooth, or the earphone jack. Pitiful. Makes me want to cancel my telenav account and just go with Google Maps.
