Need Help - Do not find a way to upload custome POI to my Roadmate 1475 T

Hi,

I am going for a long planned trip to Utah next week. Being a GPS freak, I have collected almost 300 coordinates all across the state. I have crated the .mgln file using the poi file editor and then copied the file under the USR/ CPOI directory in my Magellan 1475T GPS.
SO far everything looks OK. The biggest surprise come after that. I switch on the GPS and do not find any way to load my POIs in the unit.

I would appreciate if someone can help me to understand what might be wrong and save my trip from getting ruined.

Thanks a lot in advance.
