I have just recently updated my Nav system and have the 2011 two disc GM p/n:20980238 version 7.00 map DVD package available for sale. It comes in the original DVD NavDisc case and is in "like new" condition and has operated perfectly in my 2009 Vette. If anyone is interested, just send me a private message with your name and address and I will mail it to you. If you find that it meets your expectations, just send me a check for $65.00. If it does not meet your expectations, just return it back to me. I operate on the honor system. Best wishes.
