Summary: CAUTION: This adapter is NOT for eTrex Legend or Vista
Comment: I'm sure this thing works fine on some GPS units... but it's less than clear that this adaper WILL NOT WORK on the Legend or Vista. The title is misleading (it says "most" eTrex), the Product Description is just wrong (it says "all" eTrex). FOR The eTrex LEGEND or VISTA, you need a different adapter!!

Summary: Garmin Cigarette Lighter Adapter
Comment: A necessity for the Garmin. Used the adapter to power the unit on my motorcycle. Works like a charm.

Summary: Does what it's supposed to do.
Comment: Although the eTrexes were really designed for use in the outdoors, I use it in the car to help predict distance to go, etc., and if I have the local map downloaded to it, it has helped me out of binds on a couple of occasions. If you use it in the car, you really want this adaptor to save your batteries.
Not only will it save the batteries, but I can operate my Legend in normal mode to get better position from the WAAS data. (Battery saver mode precludes the use of WAAS and normal mode can really drain the batteries rather quickly.) (BTW, there is no scientific reason for reception to be better because of using this adapter.)
The cord is generously long. In fact, it can get in the way sometimes, but may allow the unit to be passed to the back seat so your back seat navigator can monitor it.
I have only two minor complaints. The first is the price. The Garmin Legend gives a lot of feature for the price, but Garmin seems to make up for it with the price of the accessories. It seems this adaptor should cost half what it does.
The second is that the fuse is accessed by screwing off the center of the cigarette plug, and the center piece has unscrewed itself on a couple of occasions now, leaving several small parts strewn about. I had to dig in my glove compartment this weekend for all of the little parts, and am waiting for the day I lose one for good. So be careful that the center is always screwed in.
I use this with the suction cup mount, which works quite well on glass. (But again, seems kind of expensive for what it is.)

Summary: Did the job....
Comment: This adapter does exactly what I wanted it too:
1) Save the battery while I'm in the car.
2) Increase reception; the signal seems to be stronger when I've got my etrx plugged in.
3) Easy on, easy off. No problems whatsoever.

Summary: Simple and to the point
Comment: All I require of this cable is that it plug easily into both my car and my Garmin Venture and then power my Venture. It does that swimmingly, just as it should. The only aggravation has nothing to do with the cable: when you remove the cable, the Garmin will power down unless you hit a button telling it not to. I would often have the GPS hooked up in the car, get to the parking spot, then remove the cable in order to go and and get to the geocache. At which point the GPS would turn off (because I'd forget about the power down), and I'd have to wait around for the satellites to be found again.
