BA_GS400 Posted May 3, 2004 Share Posted May 3, 2004 If your car is like my 99, then it's actually a hard-drive update, i had mine done last summer. They had to order it too. They'll want to charge you for it if you are not under "warranty", but, I believe you get 2 free updates while under warranty. Quote Link to comment Share on other sites More sharing options...
