Although Garmin is advertising the Zumo 550 as a GPS for motorcycles, looks like it could turn out to be a great in-car nav unit as well. As I mentioned in my recent review of the Garmin StreetPilot c550, the one thing I would have liked is a freshening up of Garmin's ageing interface. Looks like the Zumo just might be great. Check out the specs:

• Bluetooth
• XM NavTraffic
• XM Satellite Radio
• SiRF StarIII Chipset
• NAVTEQ Mapping Data
• WAAS Enabled

So what exactly makes the Zumo 550 a bikers GPS? According to Garmin's website, the unit's touch screen display is designed to be "glove friendly" to operate, and you can set the controls for left-handed operation. The unit is also ruggedized, and designed to withstand all the vibration you typically get on a motorcycle. It also includes special motorcycle mounting hardware, in addition to regular 4-wheel vehicle mounting equipment.

Looks like we can expect about 3 hours of battery life from the Zumo 550's internal lithium-ion rechargeable. Here are all the deets we know so far:
