Sony has extended the warranty program on its forthcoming XAV-701HD and XAV-601BT in-dash A/V receivers, which feature high-quality WVGA panel displays with full touch screen capability and universal smartphone connectivity.  Both units were recently MirrorLink certified.  MirrorLink is a standard developed by the Car Connectivity Consortium that enables the streaming of compatible smartphone screen content to in-dash receivers.  These models feature Passenger App Control, which allows an iPhone or iPod to project video and applications onto the screen of the receiver.  They also support GPS by Telenav®.  Both models are expected to be available this Spring.  The XAV-701HD will carry a 3 year warranty and will retail at $700.  The XAV-601BT will carry a 2 year warranty and will retail at $550.
