Have you tried the HP-1 while traveling and used the zip code or the GPS function to switch to different freqs?
It's currently setup in the Fusion using the GPS with a range of 0 as recommended in numerous forums
Re: bouncing/vibration see videos below. You can see the RAM + HP-1 vibrate over bumps. Both videos shot handheld with an iPhone 5, so it wasn't the most stable shooting platform but comparing both videos you can see the difference.
Video 1 Secondary bumpy road, speeds 35-40MPH
Video 2 Highway @ highway speeds. Very smooth very little to no vibration.
