I believe what is confusing to people is that when you go to the Chevrolet "build your own" web site, for the selection
Chevrolet MyLinkŪ1 Radio with Navigation2
it shows $0. However, if select it and you look at the price calculation, it adds $1795 automatically. If they are in fact allowing for a MyLink with Navigation for no additional charge
without the PDR, this would be fine and they would need the next selectable option be something like "Chevrolet MyLink with Performance Data Recorder" and show a charge of $1795. Otherwise the $0 needs to be changed to $1795.
Their "Build Your Own" website needs a fixing!!
