VAIS Technology has released a new interface that lets you add a SiriusXM tuner (included) to a factory Toyota/Lexus radio, model year 2014 and newer.
The tuner/interface package, GSR-001 works with the SXV200 tuner. It installs through the factory USB port and then requires a power and ground connection.
Satellite radio then shows up on the radio touch screen as a SAT icon.
All the satellite radio features may be controlled by the factory controls (including steering wheel controls). Functions controlled include channel and category browsing, presets and text display.
Users retain all factory installed components such as iPod/iPhone add-on, 6-disc CD changer, CD/DVD changer, rear seat entertainment or other eqipment.
