Not sure if BMW will ever add touchscreen since their solution is iDrive. Don't think you'll ever be able to get both. I thought one of the downfalls of the touchscreen is not being able to drive while typing in new destinations. I agree that iDrive is a lot safer to use while driving (although a heads-up display would be nice).

I would like to see traffic integrated into the NAV. Whats the point of using NAV if you have to sit in traffic? I'd also like to see a radar detector integrated as well.

Agreed. I can compare one of the best...the touchscreen/voice activated Nav in my 2006 Honda Odyssey...to the one in my 2005 BMW X5. The BMW Nav does all the basics just fine, but it is much more clunky to use...especially if you've used a really good one. Having said that, I'm certainly not frustrated with the one in the BMW, but it sure isn't the highlight of the vehicle...

Love my Nav!
 

Touch screen would be nice - but eRRRR the finger prints.
How many times do you need to find how to get where you are going. So the knob is no problem.
I really love the text of the Radio stations (RDS). Big TEXT, so nice.
One day I will get the iPod, that would also allow me to see the song label on the screen. Nice big text. Ya Ya. !!

Except for the glare issue, it seems pretty good, but this is my first car with nav. In fairness, the E53 has nav architecture that was designed in what, 1998? How many of us are running computers designed in 1998?

I have a feeling that the E70 will have a few new tricks to show the world.

Not really worth a new thread, but I have the nav lady voice as low as it can go and it still seems loud..normal?

I had a MDX for loaner last month and I noticed that MDX's nav interface is not as good as RL's. RL does not have touch screen but the interface for inputing the address (if you don't use voice) and menus with nav integration with idrive look-alike knob is very good. Even the screen appearance is sharp and crisp.
