Hello all. Newbie here.
I have just followed the directions exactly as catymag detailed. The JM KG 1.5 with the checksum correction must be used with FID 800. I installed it on my Garmin 3790.
I can confirm that the CitiExplorer test routing in pedestrian mode in Manhattan works as it should.
Without a reliable Garmin Map in Japan and certainly as a foreigner lost in a small city a couple of months ago, I had to turn to Google Map on my Blackberry and it was the one thing that saved me lots of time and sign language communication.
I am reminded that I cannot say thank you here and so I will not say thank you to the wonderful people here. :Animated39:
