yeah this one isnt IR, it uses the brown/white wire on the deck.. the IR ones have thsat shitty delay..
installing it sounds simple enough.. its the programming that sounds sort of shady..
"Installation is straightforward — just connect a few wires, only 3 wires in many cars. The direct connection to the stereo means there's no need for an infrared emitter, allowing the SWI-ECL to function even in bright sunlight. Step-by-step LED confirmation makes programming easy. Once connected, the SWI-ECL's failsafe memory will learn up to 5 stereo functions, retaining them even if battery power is interrupted. Dimensions: 3-3/4"W x 1-1/16"H x 1-9/16"D. Warranty: 1 year. "
any time they say its easy...it usually isnt //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
