Just found out that I may not have version 10.6 after all. I understand the update is just a nav update. My navigation is terrible (incorrect positions, won't save address, etc), but I don't really use nav so not a big deal to me. That said, would like to be current as long as the update doesn't cause issues that don't exist now. I have read a few posts suggesting 10.6 introduced bugs. For the people who received the 10.6 update, would you recommend the update, or should I leave well enough alone?
