Only a couple days after showing off some new GPS receivers, Garmin is continuing the love and announcing four more devices. First up is the Zumo 450, which is designed specifically for motorcyclists. This one's ruggedized and waterproofed for use on your hog and lets you save custom routes to an SD card and then share 'em with your fellow bikers (at least the ones who also own a Zumo, that is). The interface -- which can be used through a glove -- has over-sized buttons for safety and easier use. As far as security, the Zumo features a locking mount and the GarminLock -- a 4-Pin password theft prevention system. Next, is a pair of Nuvis -- the 370 and 670. Both these models feature integrated traffic receivers, Bluetooth, and a built-in microphone and speaker. Each includes MP3 player, picture viewer, and currency/unit converter software. The main difference is that the 370 sports a 3.5-inch, 320 x 240 pixel touch screen, while the 670 has a more generous 4.3-inch, 480 x 272 pixel touch screen. Last up is the VIB 10, a vehicle integration box. Designed to work with the StreetPilot c550, the VIB 10 connects the GPS receiver directly to your car's audio and power system, which while reducing cable clutter and freeing up your car's cigarette lighter, it however does also eliminate the ability to tune into live traffic services. Keep reading for a few pics of the other devices.

It looks like Garmin's set to release another GPS receiver intended to sit on the handlebars of your motorcycle, and like the TomTom Rider, this unit features built-in Bluetooth for streaming spoken directions directly to a compatible helmet. Though not quite as stylish as the Rider, the upcoming Zumo does offer a few innovative features not found on other models, including the ability to calculate how much fuel you have left for automatically re-routing you to the nearest gas station when you start running on fumes. You can also listen to MP3s stored on a memory card and set the unit to act as a datalogger, letting you download route history information to a PC for perusing at your leisure with Google Earth. Sources say that the Zumo will be available for purchase sometime in October, but prepare to spend around $1,000 if you want to take one of these out on the open road.
