This custom-designed S2000 solution allows you to use the factory dashboard radio switches to control your after-market head unit. It operates by sending infra-red codes to the HU and requires an IR emitter (supplied) be installed facing the head unit's IR receiver. If you prefer a wired controller that doesn't need an IR emitter, check out the Wired DCIs that work on Alpine, Kenwood, Pioneer, and Sony.
Features of the IR DCI
|Small adapter unit - easily fits behind or beside head unit.|
|Provides 9 control functions using the 5 stock dash switches. See functions chart below.|
|No complicated programming required - just set your head unit brand on the dip switches and it's ready to operate.|
|No 'delay' in button response - unlike some other devices on the market, the DCI functions operate immediately when the dash button is pressed.|
|Auto-repeat function built-in - press and hold VOLUME UP, and the volume will increase rapidly as the command is repeated. Auto-repeat works on other functions too, meaning features like 'track fast-forward' will work if you press and hold the NEXT TRACK button combo, just like they do with the factory remote control.|
|Optional Speed Controlled Volume function - An exclusive Modifry Products feature enabled by connecting one additional wire to the S2000's speedometer circuit. The DCI will then automatically raise and lower the volume based on vehicle speed. See SCV details.|
|IR Mute Disable - special feature for Alpine head units. See explanation here.|

The above chart is for all head units except Kenwood, JVC, and Clarion. Because these brands use some unusual remote functions, the DCI works a little different. Here's information on how Kenwood, JVC, and Clarion are different.

Close-up of infra-red emitter. The emitter transmits IR energy in a 180° pattern facing down. It's always best to position the emitter close to the IR receiver on the head unit.
On this Alpine the IR receiver is behind the "MediaXpander" logo. You can usually find the location of the IR receiver in the head unit manual.
