I know this is debate with no solid answer but as I'm preparing for my cross-country drive, I seem to be getting conflicting advice. Roy recommends the RX65 as his top pick (and with Ku in the US it seems to edge out the X50) and part of this seems to be because of filtering. Many of the posters on these boards swear by their V1s for highway driving and don't seem to think it's much trouble in cities (and trumps all others). Has anyone tried both? Anyone have a thought on this particular debate? Will the V1 false to often? Are people just living in the past with the V1 and not giving the RX65 a fair shot? Thanks to all!
