Bongo Fury

I have a Kenwood radio fitted in my Freda. Although there is an input socket for playing mp3 throught the radio speakers there doesnt seem to be anywhere to plug headphones in. I like to listen to the radio late at night and early in the morning and rather than disturb other campers I thought I would use headphones. Does anyone know how I can connect up my headphones to the radio?

Which Model do you have Rod?. Below is a link to instructions, but I can't find earphone details anywhere.

Not seen a headphone socket on many car radios at all (well, not for a long time ).
Why not just get a small portable radio? I got a very small one (about the size of a cigarette packet) from Lidl for £1.99 - the inbuilt speaker is rubbish, but it's fine with headphones

Thanks all - I have a manual but doesnt help - thats why I posted here hoping some expert would notice it! I've tried 2 cheapish radios but the reception is hopeless compared with the car radio. Just thought maybe a cheap radio needs an aerial outside Freda.
