 Typical values of resistor are: R1 = 22K and R2 = 1K, although some experimentation may be needed if these attenuate the signal too much, or if the audio input is not detected by the device.
+[Note, Kevin Walton, 04/08/13, Samsung Galaxy S2 did not recognise the mic with a R2 as 1K, but did recognise a mic had been plugged in with R2 as 1.5K, it also required a ferrite filter to reduce the noise.]
 Some phones appear to throw out a lot of RF noise on the audio cable which can cause interference with the radio. Adding a ferrite ring on the cable at the phone side should solve the issue. (Thanks to Jon G8KNN for pointing this out)
