I purchased a Garmin 330 GPS only to find that it had an impossible time finding satellites in our 2007 Toyota Camry Hybrid. It seems that all the electronics in the car somehow interferes with satellite reception...the Garmin works fine in other vehicles, even if it's not sitting right on the dash. I mounted this amplified remote antenna at the top right corner of the windshield and have no problem getting a strong signal. The price was one-third that of other antennas on the market. Highly recommended!

Accessory antenna attached to windshield by suction cups is out of sight (except for the wire) behind the rearview mirror and increases the signal strength to my Garmin 60cs handheld GPS. Allows the handheld to be held under the metal roof for a closer look and handed to others in the vehicle without loosing the satellite signal. I'm very pleased.

I have a Garmin Street Pilot. The car I primarily use it in has an in-windshield antenna that prevents the Garmin from finding the satellites. I bought this, stuck it on the roof, and plugged it into the Gramin and it works better than it ever has. It finds the satellites as least twice as fast and never loses the signal. Have been using this for about 6 months now with no problems whatsoever. I highly recommend it.

I love this antenna. I've been using it for my Garmin GPSMAP 60CS since I bought it several years ago. Well, recently after a long day of kayaking, watching the STS-119 shuttle launch, and then battling traffic to get home, I was exhausted and sore. I haphazardly yanked on the antenna cable to remove it from my kayak's deck bag, and the connector separated from the cable and stayed attached to the receiver's antenna port.

Oops. Truly not a fault of the antenna. I bought another one quickly.

I've had this thing on my kayak (in fresh water and salt water), on top of my car, clipped to the outside of my backpack, you name it. It has performed admirably every step of the way.

And the performance is excellent. On my last kayak outing, I was getting a consistent 5-foot accuracy on my 60CS, which I have never once achieved with the built-in antenna. Doing the Rock Springs Run here in Central FL with consistent heavy tree cover, I have always been able to get 8-foot accuracy or better.

At any rate, it's such a significant difference that I'm buying another one immediately, and when I upgraded receivers recently, I chose the Colorado 400T over the Oregon 400T specifically because the Oregon doesn't have a port for an external antenna!

One important note, though, is the connector type - choose carefully. If you have a model that has the antenna port on the back (like the 60-series), then choose the angle connector. If your antenna port is on top of the unit (like the Colorado), choose the straight connector. I made the mistake of getting the angle connector for the Colorado, and it's impossible for me to remove the connector without pliers, due to the tight connector and minimal finger space to get a good grip on it.

Also, in my experience (having had both a 9-ft cable and a 3-ft cable), if you're doing any hiking or geocaching with it, do yourself a favor and get the shorter cable. My longer cable spent all of its time coiled up and getting in the way. You could always get an extension cable for the rare occasions where you need the length, and leave it at home the rest of the time.

I have a 2007 Camry with one of those windshields that interferes with reception on my Garmin c340. Got tired of losing the satellites and got the Glisson antenna (with a 9 foot cord, didn't think 3 foot would be enough) which virtually eliminates satellite loss. I wrap the cord around the rear view mirror once and stick the rest up between the sunroof and the sunroof sliding shield. Works great up there. Didn't have to run it outside like I expected to. When updating my Garmin destinations indoors, I can now easily acquire satellite signals. which I could not do before connecting the external antenna, which just demonstrates the difference it makes.
