S Florida: factory order and Nav system

Mambomn

Thank you for the comments. Good to know that there seems to be no major issues for the factory Nav unit and that it's repaired under warranty. However, as most factory Nav systems on the 370z have been installed under 5yrs, my concern is what happens after this time when problems usually begin to appear on hard drive systems and where the factory warranty already expired? Somebody suggested purchasing an extended warranty from Nissan to hedge against possible problems, so this may be a solution, but it does add to the total cost of the Nav option ($2000 + $1500) which may not be worth it compared to an aftermarket Nav unit.
