I just purchased a 2012 XC60 and the biggest disappointment is the map update for navigation via Sensus RTI. A real pain in the neck. Any way to upgrade the Sensus RTI to Sensus Navigation? Can this be performed by a Volvo authorized dealer/service provider and at what approximate cost? I know that the quick solution is to change to a 2015 car, but there are some budget constraints so this is a no go.
