Hands-free Phone Function on Go 520
Link to phone via Bluetooth, and there is a phone handset button on the screen near bottom left. Click the button when in planned route following mode, and a panel appears offering the option to dictate a contact name (never works, too noisy in the car), or bring up the contact list on screen. OK so far.
Try to do the same when there is no route planned, and it doesn't work (no panel appears) - unless the button has already been used in route following mode since the last boot up.
It would be interesting to see if other users can replicate this observation.
