I just installed a Shaker 500 head unit with 6 disc in dash and mp3 from a 2007 Mustang into my 2004 F150. Everything works perfect except for one thing. On my stock head unit, the MEM button on my steering wheels controls moved through the preset stations. With the Shaker head unit it, the MEM button seeks through the radio channels. Any way to get it to go back to going through the presets?

 

The Mustang unit can be programmed. See if the dealer can flash the CPU to meet your desires.

 

Uhh the CPU?!? It just needs the radio to be programmed. And normally most dealers do not have the tools.
