1. Unit is generally slow to load and respond at times. No solution to fix: "It's just the technology."
2. During the map update (Feb 2011) my maps were deleted. Four days later I am still trying to get it fixed. Call the 800 number, explain the problem, get transferred to the "special" desk, get transferred to the software desk. Now they want me to hold for 20 more minutes when I've already spent 4 hours on the phone with these people! Seriously?

Would not recommend this process with a problem like this. They should have a queue or move to the front of the queue or something similar.
