Works fine, but be warned that the cigarette lighter plug contains a voltage step down converter that converts 12v to 5v. So you can't just cut off the end and hook it into a mobile installation.

I took the adapter apart and re-housed it. Now I've got mine hooked up to an ignition switched power source so I can use it to report GPS data with out draining the battery.

Bought this for our truck's APRS ham radio. Selected this model for ease of connection, wired a db9 plug to a 1/8" stereo plug and connected the GPS 18PC to the Kenwood TM-D710a radio.

Turned on GPS fx in radio and bingo! GPS icon started flashing in corner of radio's faceplate and we're sending packets with our location data.

We decided to try it on the dash instead of rooftop for two reasons. The cable was just a little short to extend out to the roof and provide me the inside routing I wanted. And, our Garmin Nuvi has always worked from the dash without any problems. Sure enough, the GPS 18 PC has worked perfectly for two weeks sending location info to our ham radio.

We dissected the cigarette lighter plug and removed the spring and button, replaced them with a pair of wires to an Andersen power-pole connector. This maintains the 5.7 volts to the gps 18, and allows us to plug into the switched accessory supply we added to the truck.

This Garmin gps looks nice, does everything it's supposed to. No surprises, no problems, works perfectly for the job.

I bought this to go with my Uniden Bearcat BCD996XT to enable the GPS area frequency switching features. It hooks up easily and worked immediately, acquiring satellite very quickly and in adverse conditions. for this purpose I'd highly reccomend it!

This is a great unit. Not many GPS receivers still come with a serial port, most have converted to USB. I needed a GPS receiver that would connect directly to a serial port and the Garmin unit was the best value for the price. It typically locks up on a satellite fix in 30 seconds or less from a cold start. I am using the receiver in my vehicle and it tracks perfectly, even in metro areas with building obstructions. I would definitely recommend the Garmin receiver to anyone who needs an inexpensive GPS solution with serial port connectivity.

Excellent GPS: quick acquisition. The software for configuring it is POOR (I wrote software for a living for 40+ years) with no help file, but you should only need to use it ONCE. Further, on the Garmin web page for this device, the "FAQ" link is broken. The Garmin web site is a DISASTER in terms of organization; it's easier to find stuff on the site by doing a general Google search and finding the link to the Garmin site. This is what happens when you let marketing people control the web site.

As reported by another buyer, the GPS18x requires 5v power, so there is a voltage converter inside the cigarette power adapter to reduce the voltage from vehicle levels to the 5v required. It would have been nice if the voltage reduction was done in the GPS puck, so that one could simply remove the cigarette power adapter and connect the power leads directly to (fused) vehicle power. In fact, if one wants that, the Garmin GPS16x-HVS offers exactly that, but it's more money, and the magnetic mount is a separate option rather than built-in (as it is with the GPS18x).

Like another buyer did, I took the cigarette power adapter apart (easy w/o damage), and unsoldered the fuse spring and side ground contacts. In their place, I soldered a two-wire cable that came out the end where the fuse and "button" contact were. I reassembled the unit and connected the new cable to (fused) vehicle power.

While there are other cabling options available for the GPS18x, the way the GPS18x-PC splits out the power from the data signals into TWO cables is nice and professional (not to mention convenient), so I recommend the GPS18x-PC over other 18x options.

The GPS is very quick to fix on Sats and lock in, does an excellent job both mobile and in house sitting on window sill. Quality, ease of use & functionality make it a winner!!!

DPRS is similar to APRS, these protocols mark your location on a map when you transmit on particular Ham Radio Repeaters (these are similar to what the police use to get extra range from there radios....signal goes to a tower and is retransmitted to other radios.

Just so it's clear, this isn't a standalone GPS unit. It sends GPS location data via a serial interface to other devices that can accept data in NMEA 0183 format. I use this with my Uniden BCD99XT scanner. It works. I have the GPS antenna inside the car under the front windshield and I have never had a problem acquiring location and GPS data in less than a minute regardless of weather, location, etc. So simply put, it works exactly as you would expect. Just make sure that whatever device you are connecting it to works with NMEA 0183 format which this outputs.

This receiver is for my second vehicle. I use the Uniden HP-1 between vehicles.
You will need the usual "Null" and "Gender Bender" to fit it to the Uniden Radio's serial cable.
Picked up signals immediatly, and HP-1 said "GPS Connected" right away.
Great price and quality.
Not enough cable to run it on the roof, but it's working fine on the dash of my Impala and Tundra.
