Can you load TOPO maps to kenwood Radio?

I have a Kenwood stereo with Garmin Navigation Software for Kenwood KNA-G510 and would like to know if there is a way to load topo maps to it?

 

So I have found these so far...

Does the KNA-G510 come with a memory card slot? I can't remember but if it does drop some maps on a card and do some trial and error testing.

 

Where can I find some free Topo maps?

 

Myself, I use the http://www.usgs.gov/ site but I get GeoPDF files from them for iPad applications and I think your Kenwood/Garmin unit uses a different file type. It's my understanding that other formats are available from them but there is a charge associated with those formats. A look at your owners manual or the manufacturers product page would provide you with the required format.
