TomTom has announced a couple of new additions to its GO range of satellite navigation devices. In addition to offering multi-touch control courtesy of a capacitive glass screen, the GO 2405 TM and GO 2505 TM feature voice recognition capabilities, instant and continuous routing, hands-free calling capability, a new easy mount system and a slim redesign.

TomTom's newest navigation units use a high speed algorithm created for instant route planning where traffic information is constantly monitored and recommendations for the best route offered to drivers. The company says its enhanced user interface makes route selection more intuitive and voice recognition for 130 navigation commands is included.

The inclusion of capacitive touchscreen technology brings gesture control to GPS navigation. Users will now be able to swipe through menu screens or pinch and zoom into onscreen maps. The units can also be paired with a Bluetooth-enabled mobile phone for hands-free chatting with incoming call alerts are displayed on the GO device.

The new devices don't have an SD card slot but come with 4GB of internal memory and benefit from a new click on lock magnetic mount which is said to offer an easier one-handed docking experience.

TomTom claims that the units should be good for up to three hours usage between charges and come with lifetime traffic and map updates.

The only apparent difference between the two models is the size of the screen. The GO 2405 TM has a 4.3-inch screen and is priced at US$269 and the GO 2505 TM sports a 5-inch screen and costs US$289. Initially available only online, the new units will trickle through to retail outlets by the middle of next year.
