Hey Mark.

I am having the same issues.   I cannot get any output on a Raspberry Pi 3 with BerryGPS.

Here is my output:

pi@raspi2:~ $ dmesg | grep tty

I really don’t have an option to disable the on-board Bluetooth to free up ttyAMA0 as suggested in the raspberry forum on this issue.

I am really hoping you can help me out on this.

Cheers mate!
