View Full Version : sony CDX-MP40 line in for mp3 player

I have a sony cdx-mp40. The unit has rca line in jacks on the back. I purchased a rca to headphone jack adaptor to hook my mp3 player to the sony deck. The problem is when I hit the source button it only selects between radio or cd. Is there some thing I can do to make the deck select the line in? do I need an adaptor.

are you sure that they are aux in? Perhaps you're trying to use an RCA preout as an aux in... that won't work.

yeah, your going to need to get an Auxiliary Input Adaptor. CHICK (http://www.sonicelectronix.com/item_3052.html)

it could be a setting under menu because on my Sony CDX-F7715X it lets me turn it off as a source check that but if it says AUDIO BUS IN onthe back it should work becasue thats wat my Sony CDX-F7715X says and it works great iPods are so cool lol.
