Re: Looking for a new GPS
The 378c and the 478c are identical with the only difference being the 378 is loaded with inland lakes and the 478 is loaded with coastal areas. Being near the Lake of the Ozarks, it would make sense for me to have the 378c. Both have the capability of using it a vehicle with the GXM30 external, XM antenna.
On the other hand, the 7200 is a nice unit. I guess what would matter is how much versatility one would like.
