Hey there,

This is kind of an old post now,

but I figured this out just the other day.

It's not the most simplified process, nothing hard, but it's certainly a hassle. Let me know if you still need this and I'll find you some info.

Good to know how it's done anyway, lots of new models out there..

Hi,

This document seems out of date in some respects, but it still does the job.

If you are having problems with how to add the library once you've made it:

For some more up to date info.
steps 1 to 8 should do ya.

That's how got I mine working...it's alot faster the second time you do it.

Let me know if you still have problems.
