OK, first of all, I am a windows person so I dont understand some of the talk that it seems you guys were born knowing. I installed Canola but I cant get into any kind of setup screens. I have an item called configure Canola under Extras but when I click on it, It opens a window that asks for a user name and password which I cant seem to get right. End of that story.
My second problem is installing Carman. That is the OBD reader that really looks cool. When I install it, it just kind of goes away, I don't see it under Extras, In fact, it didn't ask me what folder to install it in at all during installation. What now? The only reference I see to it is python2.5-runtime in the Application Manager. This only allows me to uninstall the app. I am thinking of making a YouTube video showing how far I can throw an N800.

To use carman, you also need to install python.
Python install is here:

Thanks for the help, It works now. I guess us windows guys don't like to read the directions. Now I can work on my car fine, I just wish I could listen to Canola while I'm doing it.

Try ukmp. Not nearly as sophisticated as canola, but getting better all the time.
