I have just recieved my 680 a week ago and thus far I am pleased. I have noticed one minor issue.

When viewing a contacts details it does not show their respective extension after the phone number i.e.: 123 456 7890 x 9999. Is there some setting that can be changed to correct this? All of the numbers as I had entered them are still in the same format on the desktop as it had been for the T650.

Also can anybody comment on the Garmin GPS unit for Treo?
