You are right, Martin... I just downloaded the beta, tested it with the Sirius, ice>Link, and the Bluetooth and everything works fine. The Telephone option was slow to appear in the menu but it came after some 30 seconds.

The bird's eye view is a great Nav improvement although as stated before the side streets are missing, but I do not think that this view is intended primarily for urban areas anyway. This is a very useful option in the Interstate, where you can see far away in front and sides -for example- the next service station or the exits without changing the scale. In fact, when I selected for the first time this view the Nav showed the closest Mall pretty nicely a couple of miles from where I am parked, something that I could not see before with the Map view at the same scale.

I only hope that this beta is stable in the long run. Thanks X5World!
