I'm in the process of installing my trusty Valentine One RADAR locator in my newly-acquired S60R. I'm hoping to eventually emulate/replicate the near-ideal installation I had for 14+ years in my 850, or at least come close.I'm looking for ideas, suggestions, and feedback. I found some old SS thread(s) via Search, but the pix are missing.
I was originally thinking that I'd just take a razor blade to the paint on the inside of the windshield near the rearview mirror and somehow velcro mount the unit wherever was(?) optimal, but the standard included suction cup mount (thanks, Warpedcow), up behind the tinted band, just to the left of the painted region, seems adequate (though the driver's sun visor can block laser visibility to the rear, and the V1 is not seeing one laser false alarm to the front that it always saw in the 850, in which the V1 sounded plenty of laser alerts to various benign red light sources; I'm now wondering if the S60 windshield's tinted band filters long-wavelength light more than the 850's).
I have the original/smaller V1 concealed display. I think I'm going to at least start by just sticking it (rubber cement? 'magic' tape folded sticky-side-out? something that won't permanently mar the plastic...) to the shelf in front of the instruments (possibly partially blocking the high-beam indicator) and route a dark gray or flat black wire ("phone cable") over the edge of the shelf and down the steering column.

Unfortunately, this will be rather obvious to anyone standing next to the driver's door and looking into the car. But I don't know of a better solution. Using the top of the cubbyhole to the left of the radio would be less obvious but is also not in the driver's direct line of sight while driving, and even though I'm still not sure what that cubbyhole will wind up being used for, I'm not eager to sacrifice any of its storage space.
Probably it would be better to hang the concealed display from the overhang at the top of the instruments (blocking the turn signal indicators), though that would require more time and knowledge of how to remove the plastic surrounding the cluster in order to route the "phone cable".

The lower right corner of the instruments has potential, but cable routing would still be a bit of an issue, plus being able to reset the clock (time zones) while driving is already tricky enough without that being there:

I'm also still dreaming of the possibility(?) of flush-mounting it something like this (my V1 concealed display is narrower than that one) around the edge of the instruments, though that would involve permanent modification to (ie, a 2 square inch hole in) part of the dashboard:

Now for the best but trickiest part, the remote mute button: in the 850 I removed its simpler wipers stalk and pried the flat back off its length and saw that I could just drill a hole in the end and install a small momentary pushbutton switch and route 2 wires through the stalk and down the steering column. Does anyone know if that is possible on the S60? It looks like it might be: there are 2 small phillips screws on the back of the wipers stalk; I've unscrewed them but the plastic back of the still-installed stalk did not un-latch for me... Alternately, does anyone know if the V70 wipers stalk, with its additional push switch(es?) at the end, could be used on an S60 (if so, does it come with 2 or 3 additional wires that could simply be appropriated for use with the V1?)?
The finishing touch is an OEM-looking kill switch for the V1 power, one that can be accessed without any unusual motion on the part of the driver being noticeable by someone in a car that is directly behind. The logical place for this is one of the unused switch locations in the row of switches below the HVAC controls. I know I've seen pix somewhere on SS that showed nice little black rocker switches that fit perfectly and looked right at home there, but I can't recall where they were or who posted them...
