Without trying to connect, what happens when you start MDC?
MDC opens fine and updated itself. Although it shows a small yellow icon saying "not connected" it also shows im logged in, the updates required and the icon to update but they are all greyed out. I assume it recognises my details from previous updates.
Updated my 18 year old TT GO520 using same PC and USB port with no problems. It did not have any satellite problems either. Picked up signals even in covered carport within seconds.
TT 135 Via from brand new has always been slow getting signals. Stuck it to bedroom window with clear view of the sky it showed up to 9 satellites, however when a route was input it was unable to receive any satellites.
Tried my My Linux Ubuntu OS and it recognised a USB had been input but obviously could not continue as TT does not support Linux. It said no compatible programme. This was the same PC, USB port and cable so would indicate that these work ok. looks like windows unable to recognise TT. so there is a missing link
Have tried all the TT help, instructions and videos but nothing worked Thanks for trying to help
