You just have to shell out the extra coins to have Garmin unlock them.
I have not flown the Proline, but hear it is nice. Tons of time behind the Garmin and I enjoy it for its simplicity and loads of available info.
As for LPV, depending on your operation, you must be trained on the LPV app before you can fly it. LPV's are the greatest thing since sliced bread!
The newest update to the G1000 will allow building a hold, crossing points greater than 99nm and a few other goodies.
