HK GPS 300 Maps.
I wanted to update the maps on my HK300. Foolishly thinking the maps were IGO8 8.0, I deleted the old maps and installed new IGO8 8.3.4. Now at startup everything is fine until I select Navigate. I get a error message that say's "Can find Nav file". Can anyone help me? Which maps does the HK use and where can I find them? Thanks in advance.
