Hi I'm new to the forum and was wondering if anyone could help. I've visited the forum a few times and read quite a few postings and I must say I have found it very helpful. As I get closer on getting a new G, I am still wondering about a few things. Any advice, suggestions, comments would be greatly appreciated. First, are you able to use the nav unit in the G as your driving, such as looking for nearest gas, hotel, ATM, dining, etc.? Or does the car have to be stationary? I'm debating whether or not to get nav. Second, is it a touch screen and/or voice recognition like the TLs? TIA
