GPS data logger.

Hi everyone , i am doing a project on Gps data logger. i am using a garmin 15l reciever and atmega32 as a microcontroller. Till now i am able to show the gps values like latitude, longitude, time, speed etc onto lcd. BUt am not able to log them onto a sd/mmc card.

Please help with this guys.
