What's up, guys, long time lurker here...thanks for all the helpful advice. I've always had an interest in RD's, but you guys definitely take it to a whole new level.
Just hardwired my Bel Pro RX65 with smart cord, what do you think? I think the smart cord mounting location looks pretty clean. I mounted the RD high for the best radar coverage and it's most sensitive to laser scatter from this location (trust me, I've experimented) plus from the outside you can hardly see it (so I don't have to take it down everytime I park for fear of it getting stolen). Also, I still have full use of the passenger side visor and complete range of motion for the RVM. Mounted the smart cord display so that I could mute it or change volume within arms reach.
Not sure how large the V1 concealed unit is, so I don't know if it would work, but for Belscort units that use the smart cord it's almost a perfect fit.
