I have a 2001 A4 with a double din Symphony Headunit. Its fine, but it isn't exciting. I want a unit which can play mp3 CDs, and hook up to an ipod or mp3 player while also showing info on the DIS display. I have looked at some LCD touchscreen options, like this http://www.audio66.com/product.asp?...=cat&userid=&gclid=CNXz5uaayZoCFYiD3gode3tbSA I have seen a few of these kicking about at around the £300 mark. They look really good. I want to use a good powerful HU to power 8 new door speakers. I think this should have plenty of power for that. I don't have my stereo on loud, but my existing rear amplifier is shot to bits and barely drived the rear speakers and sub. I'll probably then add a small powered sub enclosure either in the boot or a self contained job under the front passenger seat. Any views, opinions, or alternative options welcomed. I don't have steering wheel controls so they aren't an issue, nor do I have an external CD changer to worry about.
