Am very disappointed as well ! From the graphics, to the traffic jams and no-rerouting!! I had a Saab 9-3 combi 2008 model before, and its navigation, as navigation, was a lot better!! Apart the outdated graphics, it always alerted me way before of the upcoming traffic jam, had a visual icon when there was traffic jam on the selected route (green car no traffic, red car traffic on the route ahead) and suggested alternative routes, with distance and time differences!!! Not only in CH but also abroad!! The Seat navi (not plus) is just a disaster!!! You cannot avoid by any means traffic jams, sees them sometimes when you are stuck in them, never ever does it suggest alternative routes, the graphics are very outdated compared to the competition and the display is useless, since it does not show time, outside temperature, etc!! You cannot configure it to show this crucial info in a small line! So useless!!! And for traffic, you have to quit Navi and go to Traffic on the main menu to see if there is anything ahead or if the route is clear, and then go back to Navi!!! I need navi when driving abroad (DE, IT, etc), and I cannot use 4G all the time due to the high roaming costs in Europe as CH citizen ( we have no overall EU same roaming charges)...
Even in CH, it does not work properly, with 4G and all the systems. I do not know if I should do something in Settings, did not find anything though!
Cannot wait to the ios12 update so as to use Google maps, since Apple maps are worse than the Seat navi!
