Whats the DIFF between these 2 NAV Options??

[_crazi4speed_]

Sound system with Navigation, ETR AM/FM stereo with CD player, (U65) Sound system feature, Bose premium 7-speaker system, DVD navigation with GPS, 6.5" LCD color display touch screen, voice recognition, includes Radio Data System, seek-and-scan, digital clock, auto-tone control, automatic volume and TheftLock (U3U) $1,400.00


Am/fm cd with dvd navigation, bose premium 7 speaker system (replaces std/opt/pkg radio) (URB) $1,400.00

And do you think it would make sense to not get the Nav and put an aftermarket Nav? How would it look?

Thanks.

Hi there,

First, U65 is the speaker package, not the actual DVD navigation system.
U3U would be the actual system for the Corvette DVD nav system.
I cannot find URB in the Corvette RPO list.

I am guessing you saw those listed on GMBuyPower? I believe that is simply a mistake, the nav system is:

URB: Sound system with Navigation, ETR AM/FM stereo with CD player, (U65) Sound system feature, Bose premium 7-speaker system, DVD navigation with GPS, 6.5" LCD color display touch screen, voice recognition, includes Radio Data System, seek-and-scan, digital clock, auto-tone control, automatic volume and TheftLock
1 - Deletes 6-disc, in dash CD changer and MP3 playback.

As C4C5 said, U65 is the Bose speakers, U66 is the base 7-speaker setup, and both are part of a larger audio package.

C4C5, U3U was replaced with URB:
Effective 11/22/2004, the following changes will be made to the Vehicle Order Guide:

• Interior section-(U3U) Sound system with Navigation, changed RPO code to (URB).
