need map for lowrance hds7m gen2

[prossen]

Hello all.

I could use some help. I have bought a Lowrance hds 7 m gen2 and a structurescanHD. I have no map for the plotter. I have my eyes on the Navionics maps, but is it platinium or gold or + ? I'm VERY new to the 'marine world' As I understand some of the maps, your able to download other peoples sonar scans, I guess that is nice, and could help navigate safe.
(I think I'm able to save the structure scans to a log, and overlay it on the charts. not tryed it yet. )
But the main ? is wich map, and the country is Denmark :-)

regards
