Well, its been almost a year already that we have had our 2010 r/t. My question is this. If we don't buy a package from sirius, exactly what will we loose? I know sirius radio and traffic, but how is the quality of the nav without it? We don't care about the radio stations, but we do use the nav from time to time. I also want to make sure we still can use the u-connect and the bluetooth, although I am pretty sure they will not be affected. Thanks for any info.
