Figuring how few GT's are sold by dealers (maybe 3 each?), no wonder many dealers have problems figuring out the firmware update off the computer. I think I'll wait a few months until they get a couple under their belts.
Heck, I had enough problems figuring out how to do a 600 mile fluid drain on the final drive today. Three hours later and I'm a bit smarter, but not by much.
Glad your firmaware update worked out.
