trouble with GPS shield

i am using the adafruit GPS shield and when i tried download any gps code to the dem.. 168 arduino board i get this warning
Binary sketch size =6462
avrdude:stk500_getsync(): not in sync:resp=0x00
avrdure:stk500_disable():protocol error ,expect=0x14,resp=0x51
I am new to arduino so pls. help
also I ran the LCD display program and it worked fine

Try going to Tools > Board > Arduino w/ Atmega328

I did change to arduino with 328 in the tools and i still see the same error

Do you have it wired through pins 1 and 2? If so, you need to remove the TX jumper. Can you upload without the shield?

no i wdo not have the shield even connected. I try to download the program and connect the shield later. I just want to make sure the program downloads fine

Have you tried loading any other code onto the arduino?

i have downloaded LCD code and it works fine
