I have been having a problem with my turn by turn directions today. The car is able to find its location, but when it goes to download the route it will go for about 30 seconds, then the call will end and the car will say "Route download failed, retry?". It is never successful after a retry. After driving for about 20 mins, the directions pop up like i was still sitting at the start, but would dissapear after about a minute. Has anyone experienced this before?
