Greetings guys,

I recently bought a second sonar/chartplotter Lowrance Mark 4 - CHIRP and I found that it is extremely difficult to find a map for this plotter unlike my first, which is Garmin.

I would be extremely grateful if you can direct me to where I can download a map for the Aegean Sea. I heard that Navionics Platinum+ contains pretty much everything and supposedly works on Lowrance but I cannot find that either.

If you can give me some hints I will be grateful as well.
