Post any addons or improved hardware you've found.
The antenna that came with the RSNAV was pretty weak, and Google Maps would jump all over the place when navigating. I replaced it with the Fakra Male Plug GPS, and it is a small improvement. So far, I haven't had any jumps in Google Maps, so I'll stick with it until it shows problems. There are a few other antennas on Amazon that should work, so post up if anyone trys them!
