Thought I would update on what ended up being the cause in case anyone else runs into the same issue. After returning to Cabelas with the GPS and hunt chip map and talking with a couple of their people and explaining to them that I could get the chip to work in my computer but couldn't get it to work in the GPS they said they had seen it before and it was more than likely that the GPS card reader was bad. The problem was I bought the 550T on sale and they informed me it was discontinued. After speaking with the manager he was very accommodating and offered to upgrade me to the 650T for their cost of the unit. I went home and tried the chip in the GPS and again could not get the chip to work, however it continued to read just fine on my computer. I went back the next morning and after getting their expert it was determined that the chip was bad. Even though it worked on my computer, for some reason it would't read on the GPS. They opened a new chip and we put it in and it came up instantly. Hopefully this might help someone in the future.
