I still think that what you are trying to achieve requires more work and the
result will be less satisfying than trying to do the same with a vector program.

After have a look at the frame rates of existing navigation solutions i am pretty
sure that there's a cpu bottleneck in rendering vector maps on these small devices. 
The solution you are planning consumes significant more memory and cpu power 
than the usual vector solutions (as you e.g. handle/cache bitmap tiles, redraw 
certain things several times or render offscreen portions of tiles).

I am just afraid that a lot of man power will be consumed by such an approach
while this would just be better invested into more promising solutions.
