-Physical Size: 3.2"H x 5.6"W x 2.0"D (8.0 x 14.3 x 5.0 cm) (Slightly smaller than the SP-III)
-Weight: .93 pounds (420 g) (Just 2/3 the weight of the SP-III)
-Display: Finger Touch Screen, 3.3"W x 1.7"H (8.4 x 4.4 cm), (305 x 160 pixels), high contrast, 256 color LCD with backlighting (Same resolution as the SP-III screen but 0.1" smaller in each dimension.)

Waypoints: 500 with (up to) 10 character name and graphic symbol (Autorouting does not use these waypoints.) Autonumbers each waypoint but allows users to change waypoint name using remote control or touch screen.

Track log: 2000 track log points

Trip Information Page: Speedometer, Resettable odometer, Compass Ribbon (moving), time of day, driving time, stopped time, total time, Multiple Mileage Logs, average and maximum speeds

GPS Receiver: 12 parallel channel GPS receiver continuously tracks and uses up to 12 satellites. (WAAS and DGPS not included and not needed as the SP2610/2650 have automatic road lock to keep your cursor on the roadway.)

Acquisition times: Warm: Approximately 15 seconds, Cold: Approximately 45 seconds, AutoLocate: Approximately 2 minutes

Update rate: 1/second, continuous

Position Accuracy: Position: < 15 meters (49feet), 95% typical with clear sky view and good DOP

Velocity accuracy: 0.05 meter/sec (.035mph) steady state

Dynamics: 6g?s

Interfaces: USB (ver 1.1) with NMEA 0183 version 3.01 (No RS232 serial port except on SP-2650 where it may not be "standard".)

Antenna: Built in GPS antenna with external MCX-type connector jack. Accepts external amplified antenna.

Case: Rugged; fully gasketed to IPX-7 waterproof (only with the CF card slot cover closed). Remote control NOT waterproof.

Temp. range: 5?F to 158?F (?15?C to 70?C)

Data storage: Indefinite; no memory battery required

Map storage: Data cards store detailed map data. SP-2610 compatible with Compact Flash (CF) types I and II. Comes with 128 megs but can use 64 through 2048 meg (2GigaByte) standard CF cards. Note: Garmin says it cannot guarantee that ALL CF cards will work. We have tried Sandisk, Kingston, Mr. Flash, and Toshiba branded and all worked OK.

The SP-2610 uploads MapSource maps at up to 12mbit/sec using the USB 1.1 port. Your throughput will be less than this theoretical maximum speed. If your computer is fast enough and not burdened by too many TSRs you might be able to load maps at over half this maximum speed. You can load even faster using MapSource 5 and a CF card adapter in your laptop's PCMCIA slot.
