So unfortunately, unless your mp3 player has a digital (SPDIF) output, we can't give you an out-of-the-box solution yet.

I have a Renault Clio with built in radio. Modelnumber is 22DC278/62B. (picture)

I've found this page, googling the modelnumber:
http://www.javicas.8m.com/catalog.html

Now, looking at the pinout chart at the bottom, it seems the input for this model is analog (judging from the left and right inputs, digital would be left and right into one pin). Am I correct?

If so, it should be easy to connect any (normal) analog audio signal, providing the radio can be fooled into thinking a CD changer is connected, right?

Ultimately, i'd like to connect my PocketPC/Phone to the car radio and play MP3's over it, as well as using the radio as "car-kit".

Putput, Thanks for the attachment which shows how to attach an audio device to the AUX input of an Update List radio. (I want to attach the audio output of either my Tomtom 910 or my iPod, bot of which have a standard 3.5mm jack output), but I cannot find anyone who produces such a lead or who can even sell me the (green) mini ISO. Does anyone know where I can get hold of these and, when if I can only get the mini ISO separately, is it easy to connect to a lead? Thanks

Hello busheyguy, look here and search for this article number: 378652. I didn't find a prepared lead, you'll have to make a DIY one but it's no so difficult. Special tools are preferable but not necessary, with a simple pair of pincers and some patience you can fit the wires to the ISO connector. There's an even simpler solution for the jack-part. I bought a prepared 3.5mm jack extension cable, cut off the female connector and applied the ISO connector to this end, easy. BUT BE CAREFULL, the AUX input is very sensitive to high voltages (static electricity)

I know because I blew up the AUX input of my first HU. (And managed to get a new one from my cardealer under warranty)

That's great. I have placed my order. Many thanks. What is the best way to avoid static electricity?

Are you sure?
The layout of the pins look EXACTLY like the picture on his website: it has 2 mini-ISO sockets on top.

As opposed to the picture in this thread. This picture shows 3 mini-ISO sockets on top (C-section). Judging from this picture there is a fuse as well (10 A). My HU doesn't have the fuse either.

Thanks for the tip!

The most important thing is that you have to make sure that everything is grounded before you connect it, including you. You don't have to stick a wire were the sun doesn't shine but it helps . (Sorry, bad joke) Try to connect your audio device to the ground of your car (- minus) before connecting the input. That should do the trick, and of course do not touch the mini-jack connecter with your hands when the ISO connector is plugged into the HU.

Good Luck!
