So I decided to buy the map update since it was on sale and mine are probably from 21. Instructions state the truck has to be on for the whole install, which sucks but ok. Supposed to take 30 minutes so I went to the barber this morning and got there a bit early to start the install. 45 minutes later...44% complete. Well, I gotta get home, so against the instructions I drove the 5 minutes home...Up to 60%. So I left it running and THREE HOURS LATER it's not done. Apparently that's the install, why it needs to install when its on a USB drive makes no sense. So then I start the actual upgrade. Says 13 minutes remaining. 20 minutes later 11% complete. Screw that, I'm not letting my truck run for 5 ******* hours to install a simple map pack! I'm traveling next Saturday about an hour away, so I guess I'll try the install then. This is insanity, but now that I spent the $100 on the map update I want to actually finish it.
