Following on from the AA Navigator post I have resolved most of the issues bar one.
Currently if I power down the PDA and power back up the GPS shows as unplugged. Rescanning is a hit or miss affair. However a soft reset fixes it immediately. Power back on and off we go.
Have mailed AA Navigator with problem but don't expect to get much of a response as the Acer N35 isn't on their officially supported list. The N30 (Mio 168) uses comm 2 at 4800 baud. The N35 uses comm 8 at 9600 baud.
So we'll see
