NAV-TV will offers the first aftermarket back-up camera for some 2011 Volvo models, it said.It’s Volvo-Cam also adds capability for a front camera to help with parking and the ability to add FLIR night vision.The system is offered as a lower cost alternative to the factory back up option which costs $2,700. The Volvo-Cam works with the S60 and XC60. NAV-TV developed a module that “talks” to the CAN bus to allow the aftermarket add-on.The system links to the cars’ 7-inch in-dash LCD screen. It comes with a rear camera and module and gives you the option to add a front camera and night vision. You may also turn on the cameras while driving. Pricing will fall well below the factory option and will be announced next week.Source: NAV-TV (http://www.navtv.com)http://www.facebook.com/pages/Nav-TV/100969669982621-
