NavTeq CD/DVD updates
What is the deal with Porsche and NavTeq updates? On my BMW's and MB's I simply order the DVD from NavTeq once or twice a year. My 06 C2S was delivered to me in July with a 4Q 05 DVD - apparently the latest version (??) I called NavTeq and they advised me that updates are only available from the local Porsche dealer. Is this true?
