LK8000 map files?

I am anticipating flying the USA Club Class Nationals in Hobbs, NM
at the end of June. I am using an Avier/V2 PNA running both
SeeYou (licensed) and LK8000 programs. I have gone to the world
wide turnpoint exchange to get the contest data points, but I am
looking for where to go to get sectional and other maps, etc in the
proper digital format to download onto my PNA. I prefer to use
LK8000, and I was wondering if someone out there can point me to a
site where I can download the correct map data from?

Thanks,

RO
