go to the LX navigation website, www.lxnavigation.si, click on LX
Navigation and on downloads in the next window, then manuals on
download menu. You can find a manual for all the products there in
..PDF

If you are concerned about having a backup system keep the VL.
Otherwise, the 5000 will do everything you want and then some. I have
a 7000 and can run any IPAQ nav program. The data stream output has
to be set to winpilot. I believe the 5000 is virtually the same.

Wings and Wheels also should have the manual on their website.
