WHT Z06 Modifications:
Navigation Radio Upgrade
There were two main versions of the C6 navigation radio, 2005-2010 and 2011-2013. The main difference is the newer radios support and AUX input jack and USB control of newer iPods.
Another difference is the map nag; older radios display a popup the first time you use the map in an ignition cycle not to operate the navigation screen while moving. The 2013 radio does it less often. According to the 2013 Chevrolet Corvette Navigation System manual, "Every 50 times the vehicle is started and the navigation system is turned on, the Caution screen appears." In practice I've found it always does if the car is in accessory mode.
Here's the list of 2011-2013 related parts:
GM Description 20856087 navigation radio (U3U) 2011-2013 22828130 navigation usb cable 22787173 AUX/USB center console wiring harness 25832462 AUX/USB center console receptacle
In addition you need fabricate the AUX input harness and add it to to the existing navigation radio connectors. And also find somewhere to mount the AUX/USB center console receptacle. Depending on the color of your center console you find a new one that includes a place to mount it.
Delphi Num Description 12064763 1 6-way Metri-Pack 150 unsealed male (gray) 12064765 1 TPA for 12064763 (optional) 15359163 5 Metri-Pack 150 male terminal (gold plated) 12146447 5 Metri-Pack 100 female terminal
The 2011-2013 navigation radio is bluetooth ready but you also need the 2011-2013 OnStar (VCIM) module and left steering wheel control switches.
GM Description 22898987 OnStar/VCIM module with bluetooth 15938939 Bluetooth antenna 25862864 steering wheel switch (phone)
Used OnStar modules usually come the bluetooth antenna attached.
A difference between the early and late OnStar modules is that the 2005-2010 version has seperate coax cables for the GPS and GSM antennas. The 2011-2013 version combines this into one cable.
Another change that happened when the 2011-2013 navigation radio came out is that the A piller microphone was updated.
The original part mumber is GM 15285919. The new part (GM 15916146) is designed to be more directional.
