Overview
The MOST-HUR (Head Unit Replacement) allows the user to install a feature-rich aftermarket
radio while retaining the factory amplifier and converting audio signal to the factory fiber optic
system. This is the fastest and easiest way to upgrade sound quality and features without
performing “major surgery” to the vehicle. The HUR module also provides Vehicle Speed Sense
(VSS out), 12v Reverse (out), hand/foot brake (out) and Illumination (out) for convenience.
Kit Contents
Module Programming
To download radio specific files, go to www.navtv.com
and find the product page (type the kit number in
search bar, go to product page) and click on the ‘files’
button. These files are designed to make installation
easier. If you do not see your radio listed, you can use
a generic file to interface with the M.O.S.T. amplifier,
but not retain steering wheel control.
*Note: Only Alpine or Kenwood are officially
supported for retaining steering wheel controls.
*Note 2: When adjusting volume is needed (factory
amplifier gain control), change in increments of 5.
*Note 3: Fade control is not available due to factory
system limitations.
