A while back I updated to the 8.50 map which resulted in a loss of traffic and live services and (after many attempts by TomTomto fix) in a total meltdown of the unit. I got a new unit from my retailer which I have not updated in any way. Everything seems to work fine. I was told by TomTom support to not do anything until the issues were worked out. Does anyone know if it is safe to perform updates yet?
