I have tried the special version of copilot 7 and tt7 and have noticed Lag. When turning onto a road or exiting of a roundabout there is lag of about 2 seconds for the software to workout my position. The speed read out is also slow to pickup up actual speed changes. None of these problems were present on my td1 and was more real time. I have hard reset the device and only installed one of the navigation programs at one time.
Anybody have any ideas as I have sold my td1 and the td2 is not reliable for navigation.
