The OEM 18 GPS Series all require different input voltages (see list below):
• 18 USB: 4.4 - 5.5 Vdc
• 18 PC: 8 - 30* Vdc (Automotive supply from cigarette lighter jack)
• 18 LVC: 4.0 - 5.5 Vdc
* It should be noted that the OEM 18 PC unit has a cigarette lighter adapter end that converts the 12V DC (from the cigarette lighter power source) to the input voltage required by the GPS unit. If you remove the cigarette lighter end and then hard wire the GPS to the 12V power source, you WILL burn out the unit.

Garmin GPS 18x PC High-Sensitivity Description The
Garmin GPS 18x
is a high-sensitivity GPS sensor targeted to OEM clients for use in automotive, fleet vehicle, and electronics applications where a small, highly accurate GPS receiver is needed.
The Garmin GPS 18x is high-sensitivity, WAAS-enabled GPS receiver and is available in either asynchronous serial or USB 2.0 versions, and comes with an integrated magnetic base. The puck-like receiver is 2.4 inches in diameter and weighs just 3.5 ounces, making it an ideal solution in applications where space is at a premium.
The PC and LVC versions both default to output data in the industry standard NMEA 0183 data format, but may also be user programmed to output data in the GARMIN proprietary format. The USB version produces data ONLY in the GARMIN proprietary format. This means that the OEM 18 USB can only function with the Garmin mapping software on a computer. A pre-bundled package is available which contains the OEM 18 USB and the Garmin City Select USA Software.
All three versions of the GPS 18 come complete with non-volatile memory for storage of configuration information, a real-time clock, and raw measurement output data for sophisticated customer applications. The LVC version additionally provides a pulse-per-second logic level output whose rising edge is aligned to the UTC second within 1 microsecond. The USB 2.0 full-speed version of the GPS18 is also compatible with USB 1.1 full-speed hosts.
