In hindsight I would have put quieter tires on my TDI SEL. The tire noise is a real problem and quite surprising given the quality of the car otherwise is very nice.
I also was surprised by how very sluggish the RNS 510 screen is... It seems like the system has. Avery very slow CPU. Every selection seems to take 2+ second, even if it's a seemingly simple matter of entering a phone number using the numeric keypad
I love everything else about the car, especially the incredible highway mileage. I routinely reach 47 mpg.
