Just got the response from TomTom. I suspect this is lower level customer support and a canned response. Not very good.
Dear ,
Thank you for contacting TomTom Customer Support.
I regret to inform you that the Palm Treo 680 is not supported for use with TomTom Navigator 6 software. We are constantly testing and adding new devices to the list but we are not able to say when ,or indeed if, specific devices will appear on the list.
Please keep an eye on the below link over the coming months for further information.
