I recommend the Garmin GTM 36 TMC Traffic cable as an accessory. It receives traffic information and causes the navigation system to automatically suggest an alternative route in case of traffic jams. Works perfectly, at least in Europe.
Have fun & a good trip!
You can see both, the 3 picture shows a turn-off 2 km ahead and indicates which lane to get into, at the turn-off itself it shows the traffic sign etc.
Reception of traffic information via Bluetooth is with the S version, with the D version it is also via DAB.
Yes, the information is correct and applies generally to all Garmin navigation products. For more information on map coverage, please visit the manufacturer's website: http://www.garmin.com/de-CH/maps/preloaded-maps#All
