I was thinking today that it would be cool if I could control my Kenwood MP919 with my cell phone (Sony Ericsson T610) via the infared port. Any ideas on how to go about doing this?
I don't know if the regular IR output of phones is strong enough to be received by the HU's receiver.
you could start by checking the strength of the IR port by pointing it along side of your HU remote towards a digital camera (while watching the viewfinder on the digital camera) and see if your Cell phone's IR bulb is near as bright as your HU remote's IR bulb.
