Last weekend, we were out of town, &and used GPS. I set up GPS with the address of our destination before we left. I was sitting on the passenger side . I was looking for something else to finda different address, but it wouldn't let me do anything while it driving, so when we stopped &and park ited, &and it allowed me to change it to anything I wanted. WI wonder why is that? is. For Tthe last two days, I have been reading the manual book about navigation preferences to see if Iit can find it to allow me to change the address while driving, but I couldn't find it.
