Bare in mind Sergey has the 2nd gen rns-e from iirc a 2011 car so I'd expect the gps internals to be a bit more advanced in terms of getting and keeping a good signal. I'm not aware of any changes to the antenna tech that would make swapping it worthwhile though. There might be a newer chipset but whether it makes an appreciable difference....
