Hi there,
I'm doing a postgraduate course related to product design and one of the requirements of the course is to design the user interface for an in-car nav system.
If you'd like to take a look at what I've done so far and send me some feedback, I'd appreciate it.
The presentation is at
http://www.zooming.info/autonav
Overall it shouldn't take more than 15 minutes to review the design and send comments, unless you type very slowly or get interrupted a lot

.
Thanks in advance,
Mary S.
