I have a Go500 and installed navcore 8.412 and works fine except that when i pair via bluetooth with my phone i cannot neither hear nor be heard when i am talking with it.
How can i work it out ? Any suggestions ?
Also, in case you're wondering why the device has bluetooth, it can only be used for transferring files - the same as my old v1 ONE model.
The Tomtom Go500 CAN be used as a bluetooth handsfree device.

The microphone is located in the mount - have you got the correct mount for it ? You can also plug in an external mic into the mount.
