TT Go 6000 - Very slow drawing of map on my screen
I have a TT Go 6000 which when I bough ran just fine. During navigation the on-screen map was fluid and smooth and all the graphics were displayed as I would expected (I think this is called 'rendered')
For the last 6 months, maybe a little loner, this has all changed. The navigation takes an age to calculate the route and when the nav does begin, the screen graphics as I drive along struggle to keep drawing the map. This results in blurred parts of the map, unnamed roads and a general laggy experience.
The map is West Europe Zone (about 5GB) and it installed to the internal memory. The device is running live traffic and the speed cam database.
