» Garmin StreetPilot c580 Car Navigation GPS Review |
April 9, 2007
Garmin StreetPilot c580 Car Navigation GPS ReviewGarmin has been designing GPS equipment since 1990 - which is a considerable timeframe for the relatively new GPS consumer market. Still seeking to expand their product line, Garmin is planning to move into marine GPS systems with their recent purchase of Nautamatic Marine Systems Inc. Garmin’s products are well worth considering if you’re looking for the best car gps system for your money.
Although priced higher than the popular c300 series, the Garmin c500 series has added value with Garmin including numerous premium equipment and functionality improvements such as; SiRf GPS receivers, brighter displays and an integrated traffic receiver. All the c500 series come with maps preloaded in the some 700Mb of internal storage, so that they are conveniently ready for use right out to the box. SiRF Star III GPS Receiver ChipsetThe c580 Garmin StreetPilot’s GPS functionality is provided by a SiRF Star III chipset. The SiRF Star III family has proved a watershed innovation GPS chip architecture by offering impressive performance improvements to the GPS receiver manufacturing industry. They have also been adopted by other major GPS manufacturers including TomTom and Magellan. The SiRF Star III offers faster fix times, higher signal locking, higher tracking sensitivity and lower power requirements.
The SiRF Star III chipset is a WAAS enabled (which improves accuracy) GPS receiver. In 2003 Garmin was actually first with a WAAS/GPS navigation certified integrated avionics unit. The SiRF has position accuracy down to 2.0m, velocity accuracy of less than 0.01 m/s and hot and warm autonomous times to first fix (TTFF) of less than 1s and less than 35s respectively. The c580 has an internal GPS antenna however, it also has an MCX-type connector for hooking up an optional external GPS antenna. Some good news for GPS consumers is that there is plenty of competition pushing for lower cost and higher performance GPS chips. Texas Instruments have just released the smallest GPS single chip, the NaviLink 5.0, which has a footprint of only 25mm2 and is expected to make GPS available in even more mobile phones. Texas Instruments news release states that the chip will provide performance similar to SiRf with fast “time to first fix” (TTFF) in weak signal conditions typical in metropolitan areas and deep indoor environments. Transreflective TFT Touchscreen DisplayThe c580 has a 3.5 inch transflective TFT touchscreen display with a resolution of 320 x 240 pixels. It displays 64K colors and has an LED backlight. Transflective LCDs are used for displays to be used in direct sunlight - as a GPS automotive displays are at times. In low light (indoors) transflective displays use backlighting. In bright light (sunlight) they absorb the sun’s rays and utilize them to boost backlighting making the display legible and reducing power consumption. Only the area of the display exposed to sunlight increases its light output making the difference in brightness between the shaded and lit areas far less than would be the case for a transmissive display. Transflective screens are a more expensive option for manufacturers and they also lack some of the sharpness and resolution of transmissive displays can produce but, if you can see the display it’s a moot point. 2D and 3D perspective views are available for viewing maps. The touchscreen is used exclusively for GPS operation with an on/off switch and rotary volume control knob being the only other controls. Now that Apple’s boss, Steve Jobs, recently announced the iPhone with its ‘finger touch’ operated touchscreen. Expect to see more rapid adoption of this very flexible technology in other consumer electronics products. The c580 can be color customized with separately purchased color faceplates. For clear voice prompts the StreetPilot c580 has dual integrated speakers. If you want to plan your route while out of the car, the c580 has an internal lithium-ion battery with a very respectable 8 hour life. A 12-volt power adapter is included for in-car recharging. Users can search for addresses and points of interest (POI) and can also upload their own POIs. A useful selectable feature is a proximity alert which notifies the driver of upcoming custom POIs. Up to 500 waypoints with name and graphic symbol can be entered. Software features include a trip computer, resettable odometer, timers, average and maximum speed outputs. GPS Location Based Services through MSN DirectA 12 month free service subscription to MSN Direct is included with your Garmin StreetPilot c580 purchase. MSN Direct brings location based services information direct to your GPS unit. It’s available in 100 of the largest cities across the United states (check service coverage). MSN Direct location based services currently available include:
Location based services can be expected to rapidly expand with GPS penetration of mobile consumer electronics devices - particularly mobile phones. Another automotive GPS device with MSN Direct capability is the Garmin nuvi 680. StreetPilot c580 MP3 PlayerGarmin have included music player functionality into the c580 with a built-in MP3 player. It has some useful menus with users able to see album art and able to browse music by the artist, album, song or genre. Music is loaded on the SD card and can be dragged-and-dropped. For better sound it’s possible to wire the Garmin StreetPilot into your car sound system using an audio output jack. Bluetooth Wireless TechnologyBluetooth wireless technology enabled cellular phones can be combined with the StreetPilot c580 for safer hands-free mobile phone operation. Incoming phone calls are displayed on the c580 and a tap of the display accepts the call. There are both internal and external microphones (included). As with other systems, any other audio is automatically muted during phone calls. A handy convenience is being able to access phone numbers associated with the POI making it simple to call ahead. Operation and GPS MapsGetting started with the c580 is easy as it comes preprogrammed with highly detailed City Navigator NT street data of the entire United States, Canada, and Puerto Rico. The detailed maps contain information on highways, interstates, business and residential roads with attributes such as turn restrictions, speed categories and other navigation features There is an SD expansion slot for adding other maps. The map database features some six million points of interest including hotels, restaurants, gas stations, attractions, entertainment, shopping, emergency services, post offices, camp grounds, movie theaters and ATMs. One way to navigate is to select a POI by touching its icon on the display screen. To make life even simpler Garmin has provide their free POI Loader software (which can be downloaded from their website) for you to import customized POI. It provides the ability to upload POIs created by others from your PC to your Garmin unit. Having selected a destination from the touch screen interface, one is directed by Garmin’s text-to-speech functionality which tells users the name of the street, when to turn, and in what direction. Missing a turn is not a major problem as the c580 automatically calculates a new route to the selected destination. The Garmin StreetPilot c580 comes with Garmin Lock which is an anti -theft feature that disables the unit from performing any functions until enter a specific 4-digit PIN or take the unit to a predetermined location. Integrated Traffic ReceiverAn FM TMC traffic receiver (GTM20 North America or GTM21 Europe) is included with the c550. Users see congested areas color coded on the map displayed. Avoiding a traffic delay is as simple as pushing a button to calculate a new route around problem spots. The traffic receiver is a small, FM-band traffic receiver which is connected to the car radio/antenna system to provide real-time Traffic Message Channel (TMC) data. TMC data provides swift, accurate notification of situations impacting traffic such as accidents, road construction, police and emergency services. Digital traffic data is available from specific FM broadcast stations in a fast growing number of major metro areas throughout the United States and Europe. Traffic alert service subscription costs vary with different locations. Optional SoftwareOptional software is available on SD cards allowing extra features to be added to the c580 without reqiring connection to a computer. Software applications include:
