    Quick question about linking a head unit to a cpc

    Hi everyone,

    The other day I purchased my friend's eclipse head unit that he was selling for a decent price ($50). Unfortunately, literally hours later, I stumbled across the idea of installing a car pc. So, my question is: is there a way to hook up a head unit to a cpc so I can use the deck as a cd drive and switch songs and such with physical buttons but also have a touch screen where I can view the play time and volume? Or will I just have to get rid of the head unit? Thanks for your input!

    You can keep the head unit and connect the PC to it, if the headunit has an aux in. Its simply a matter of connecting the line out from the computer into the aux in jack on the headunit. When using it as a CD player/radio, you use the HU and when playing mp3s or whatever, you have the HU set to AUX.

    That being said, you don't really need a HU for a carputer, there are advantages and disadvantages to having one but its really up to you if you use one or not

    Also, maybe connecting a fusion brain/arduino to the common buttons (play, rewind, ff, switch radio stations), connect the output to your line in on your computer and control the headunit through the carpc.

    That's a great idea. Do you know of any links where I can learn how to do that?

    The manual for the fusion brain is here. If you look at the headunit's circuitboard where the button go on top of there will be 2 or 4 solder points. When you press the button it will connect the points and create a circuit. I am guessing that you can solder the points on the left to input on fusion brain, solder points on the right to output and create a program the when its run, it will let the input goto the output.

    while the fusion brain is a good idea, some headunits use a specific resistance for certain buttons-- meaning that there is no easy way to just tap into them-- this could cause the resistance to change, and then the button wont work at all. but if your HU doesn't have this, but is a removable faceplate, you would need to add wire to the buttons, which would make the faceplate non-removable. and the faceplates that i have taken apart/modified, are not easy to add wire too-- the clearances within the cases are very slim(i remote mounted a kenwood faceplate on a scooter ).

    if you are truly interested in adding a carputer, it would definately be a lot easier to replace the HU with a touch screen-- so you don't need to mees with soldering any buttons.
