....mount the main unit?
IOW to *me* the remote display seems like a waste unless you are mounting the main unit permanently, say behind the grill or such and that would be a major problem in dealing with heat and the elements etc.
IOW how do you mount it out of site?
FWIW I have a Mustang vert and I wired up an RJ11 to the mirror light power and ground and used the 3M locking strips on the top of the detector and also on the plastic cowl behind the mirror.
This way I can remove the V1 even though you really can't see it anyway unless the top is down.
I would like to put the remote display up there, but where can I mount the main unit where it won't get destoryed by the elements etc.
One thing I can suggest to Valentine is to make the top of their next detector flat as it will allow using 3m or velcro strips more effectively.
