I know about the 201, and I'd really like to spend less than that. All
I'm after is a GPS input for the D7; if I want a display, I'll use my
eTrex.

It's extremely unlikely you will find what you are asking for since
faceless devices, almost by definition, are used with external devices
(and therefore with external power sources). The self-contained
battery-powered devices are intended for stand-alone operation, and
therefor have local displays. <br>
<br>
The Foretrex is very similar functionally to the eTrex (I think it
actually uses essentially the same firmware and displays), but it is
much smaller and lighter than the eTrex which is why I suggested it. <br>

I suppose you could screw or Velcro a Garmin GPS18 or similar to the
top of a 4-cell AA battery box and then place 4 MNiH rechargeable AA
cells in it. 4 x 1.25 VDC per cell would produce 5.0 VDC which would
be a direct match for the GPS-18 without inefficient regulators. The
GPS18 only draws about 80-100 mA once it boots and locks so 2000-2500
mAH AA cells should easily power the device for 10-15 hours at a
time. [Don't try this with normal non-rechargeable alkalines since
you would be producing 4 x 1.5 VDC for a total of 6VDC or higher out!]<br>
