Although there are several posts that touch on this none seem to quite explain what is happening with my situation. I have written an app which captures NMEA data, I'd like to save this in a form that I can import and display using MapPoint 2004. My Lat/Lon however does not see to match up, I figure this is related to the format but I have tried various formats without any luck.

An example of the NMEA data is:

$GPGGA,163519.000,4248.7815,N,07106.2886,W,1,03,02 .8,00042.4,M,-32.8,M,,*5D

This implies LAT = 4248.7815 N and LON = 07106.288 W

If I import this "as is" MapPoint is way off.

I have tried 42.48.78N as mentioned in one post, also the decimal equivalent of 43 + (48/60) but nothing seems to quite hit the right spot.

Can anyone tell me what format these co-ordinates should be in to import accurately into MapPoint?

Thanks in advance for any help.

Chris.
