2001 Pathfinder w/factory NAV

[harpethriver]

I have a 2001 Pathfinder LE w/factory NAV. The head unit swivels out, and on the right side fixed in the dash is a strip with the manual climate controls. The climate control is a part of the GPS with touch screen functions also. The manual control buttons have all broken off, so the climate control must be activated by using a pointed object to depress the pad where the buttons should be. They will not just glue back on. Does any body know of a fix, or a shop that works on this unit? My understanding is it's the same unit as the QX-4 also. If there is no fix, anybody know of a unit for sale?
