Help? Brushpiles on Humminbird

Trying to put Corp of Eng. Lat/Long. on Humminbird fishfinder using HumminbirdPC. It will not accept the numbers I put in Keeps changing them. When I look them up on Google earth thay are somewhere other than Oologah Lake.

I want to put 2010 and 2011 brush pile on the Humminbird FF. Hoping not needing to set it up one number at a time.

Thanks for your help!

diffrent coord. formats

He's right MT, you have to convert the files. I think the files were taken with a hand held GPS. Not sure why the Humminbird PC won't convert them, I used the Babel converter. The link to the GPS Bable converter is listed in this thread.

I talked with Jason with Oologah Corp of Eng. he helped me change HumminbirdPC format from degrees to decimal.
So now HB will except the Decimal numbers. Went to Preferance/position format to change the system.
Thanks
