    Default Constant navi Disc Read

    I know the book says the Navi will access the disc reader on start up briefly, but my 09 Tahoe LTZ chatters almost all the time. Navi works fine, but the constant disc access is annoying....any recommendations/solutions?

    Mine does that as well. Probably wouldn't be so bad if it wasn't so noisy...

    GM just needs to use the complete NAV system they have in the CTS. The NAV in the trucks is a couple years out of date in pretty much every way.

    HDD-based Nav is the way to go!
