I am not IFR rated but plan to start training. I have an experimental
equiped for IFR with Garmin 300XL GPS (+ VOR). It has an expired
americas database card. Is that sufficient GPS IFR for US territory?
Or should I get USA specifically and whats the difference?

For a production airplane, there is an AFMS Approved Flight Manual Supplement
that spells out the limitations of use, like whether the database has to be
current, etc.

Not sure what happens with Experimentals. Do you need to get your receiver
approved for IFR from OK City? Do you submit a draft AFMS when you do that?
