HA! We misplaced our Roady 2 somewhere at the hospital and no one returned it to lost and found. Our car has the Roady 2 Car kit installed by CarToys which cost $320 for installation. Unfortuantely, the Roady XT is not compatible with the prior car kits, which means we would have to pay for Roady 2 car kit removal and new Roady XT car kit installation, meaning a whole nother $320 or more. Something so trivial as this. Therefore we cannot use new technology... Our only economical choice is to be stuck in the past replacing the lost Roady 2 with another Roady 2.
