how the hell do u install these

(not to sound stupid but why do i have a feeling im missing something, they come with velcro tabs but do those stick onto the windows or not? the dealer is supposed to print out something from a cd but guess what they didnt. so far i am not too pleased with pacificbmw service for parts

they forgot one part, its taking nearly a month to get my running boards delivered

(2 weeks b4 they ship the dam things and another 10 days for delivery) and my profile 2000 is broke (possibly ups)
