Hey guys,
it was a long winter and as I got asked several times to build something like this,
I finally did it.
I built an AUX input for MP3 players / iPods for both - Craig and ASI radios.
First I checked the market, but all I found were mono adapters or stereo with
manual switches. And of course there are those radio transmitters that only
work nicely if there is no radio station on the same frequency.
My goal was a simple system that only requires the user to plug it in and to push play !
To do this, I have to install an extra little PCB into the radio, a few wires soldered
into it and a headphone cable and connector routed thru an existing hole on the
rear of the radio - that's it.
The radio keeps all its original functions and all modifications are reversible.
As soon as a music signal is detected at the input, the volume is turned down,
the input source switched to AUX and the volume is turned up again.
The sound is great - especially compared to radio or tape.
When there is no more signal detected at the input, it switches back to
radio or tape after a few seconds.

Also interesting especially for europeans:
Check out the frequency - the original radios can't handle even
frequency steps and therefore many radio stations can't be received.
I can change this by swapping a chip inside the radio.
I have done this successfully on at least 10 radios so far - both,
ASI and CRAIG.
Feel free to contact me if you're interested in these modifications or
if you have questions.
