i went to look at navigation units yesterday and I learned some new things. On some of the units with built-in navigation hard drives, you have to send the hard drive unit out to be updated like the Pioneer Z3.
I looked at the new Panasonic Strada and was told it is very similar to the Pioneer Z3, with 3D navi interface. The 30GB hard drive is strictly for navigation, making it process a lot faster and when it comes time to update, an SD memory card can be purchased from Panasonic to update your system. The price is also lower than the Pioneer Z3 unit at 1800 dollars. Still very expensive, but another one to add to the list. Now I am more confused.
I am stuck between the Eclipse 6610, Pioneer D3, and the Panasonic Strada.
Any HELP???
