Neat Stuff for   (RioCar) Owners  

"Hijack" Menu System, with VolAdj, IR-Translate, and much more!

This enhanced version includes a new front panel menu system for controlling the automatic volume adjustment and tons of other stuff. There are separate VolAdj settings for home/car use, preserved over (most) power cycles (initially "Off" after installation). VolAdj options include "Off", "Low", "Medium", and "High", using values suggested by tfabris ("FAQ-Master").

To access the Hijack menu system, press and hold-in either the rotary KNOB, or the (Rio remote) MENU button, until the menu appears. Alternatively, press/release the (Kenwood remote) CD button three times in succession to activate the menu. Once in the menu system, navigate using either the KNOB, or the NEXT/PREV track buttons on the remote. To activate a menu selection, press the KNOB (or CD or MENU button on the remote). To exit from the menu, either wait 5 seconds, or press the front-panel TOP button or (Kenwood remote) '*' or (Rio remote) CANCEL button

Most menu functions utilize the same buttons (KNOB, NEXT/PREV track to move around, CD or MENU to select, TOP or '*' or CANCEL to quit). The menu system has grown considerably since its introduction, and now sports numerous features (click for a list).

	supress_notify=1                      ;for use with [output]notify=1

Hijack has built-in FTP and HTTP servers for remote access, and remote playlist browsing capability for use in conjunction with web browsers and audio playback software. To access this feature, just point a web browser at http://your.players.ipaddr/ and click on the link at the bottom of the page.

There is also an evolving ioctl() interface for binding userland extensions into the menu system. If you want to add your own userland application to the menus, check out the comments at the top of hijack.h for details.

There is now an excellent Hijack FAQ hosted at RioCar.Org

Is This Safe?

But even if it does mess things up, just reinstall the original official software (a .upgrade file) again, and it will restore your player back to it's pre-experiment condition. -- Mark Lord
