Garmin GPS18x OEM version
What more to say? It's from Garmin and it works great, like all Garmin products. This model (GPS18x) is the OEM version, designed to wire in to your finished product. If you can't use the Hirose connector on the leads you can replace it with your own connector which does not compromise the warranty. It runs on 5VDC and provides a Pulse-Per-Second output. The outputs are faux-RS232 level so you will need a RS-232 port to communicate with it; Garmin offer a USB version if that's what you need. We've built this into hundreds of final products with very few issues. It has quite fast "cold start" satellite detection, usually less than a minute. "Warm start" is usually less than 15 seconds. Reception is great, even when in a cityscape of urban canyons or inside wooden buildings. I will keep buying these as long as Garmin keep making them.

Works as described
Unit worked as described. Technical resources (manual) can be found on Garmin's website. Bummer thing is I did not read this until after I purchased it. Garmin GPS 18x USB does not transmit NMEA sentences, only garmin sentences. The Garmin GPS 18x LVC does transmit NMEA sentences, so I will be selling this and purchasing the latter.

Great short-term deal
Great deal. Has a nonstandard connection to fit an old 2-way radio, but most people cut of the usual OEM connector anyway. Old stock, so needs firmware update if you need the right date from it.

Works with fewer and fewer devices as it "talks" Garmin proprietary which makes things difficult.
Unless you can create virtual serial ports on newer pc or have old Garmin stuff you can use this with , stay away from USB model.
