Vector rendering problem

Hi.
I'm wanting to use my blackberry to view high detail maps such as odnacne survery maps to help me plan walking routes when on the move. I'm having trouble finding a good mapping system that works on it.

http ://maps.the-hug.net/index.php

(remove thespace between http and :// Sorry for posting a link on my first post but it isn't spam!

This site has good OS maps but my blackberry says it doesn't support "vector rendering" so it will not open.

Is there any way round this to be able to view these on the blackberry?

Thanks

Can anybody shed any light on the problem?

thanks
