Hi, I have bought an Fm transmitter for my RH10 ( Irock 450Fm on ebay ) and I have a very correct sound with it. I plug it on the cigarette ligher to switch on the transmitter (I can put a dry cell too but the autonomy is very short with it) and I plugg the jack on the remote of the Md. (I can take some pictures if you want) It's work very well if you can find a free frequency (88.1 or 88.3 in France). Waou, my first post on the famous MDCF ! (great job by the way ) And sorry for my english... http://cgi.ebay.fr/NEW-iRock-Wireless-FM-T...1QQcmdZViewItem
