My dad was playing with my 276c, and he told me to get him one, or get the newest model out. Well after doing some research, I found out something very odd. They are all identical. The 276c was released 5 years ago, and Garmin still produces them.
Don't fall for Garmin's marketing ploy of releasing "NEW" model numbers with inflated prices.

Besides the 276 lacking XM weather, these 5 gps systems are EXACTLY IDENTICAL.
The 278, 378, and 478 all come with the navigational package (with speaker and street software) that you can purchase for the 276/376 for $160.00. The 278, 378, 478 have "pre-loaded maps" that become worthless after a couple years, and you end up having to buy a large memory card anyways to store the updated software.
Pricing:
276c: $449.00 + nag kit = $609.00
376c: $699.00 + nav kit = $859.00
278: $755.00
378: $769.00
478: $749.00
