anyone know the weight of the stock navi system in the evo x?

 

It's not light, that's for sure. I'm going to say, but this is just a guess, at least 10 pounds, but probably less than 15.

 

The stock navi only consists of the MMCS and the GPS antenna. I think we can call the antenna neglible. I don't really have a scale that can measure the weight of the MMCS alone, but my bathroom scale sees 5.5 lbs of difference between me and me+MMCS.
