Hi guys, I've read all the recent threads on the forum regard the RNS-E upgrade but I still have a couple of questions. 1. Is eBay the best place to buy the latest model from (chrome knobs apparently!!) and how much should I be looking to pay? If you could link to the version I am after on eBay just so I have an idea that would be great. 2. Will I need to buy a cage for it to sit in, or does it sit in the one the symphony 2 sits in? 3. I have ordered my S3 with the Symphony 2 upgrade which has the 6CD changer, if it is possible to upgrade to the AMI, and if so does the CD changer need ripping out? 4. After installing the RNS-E (which I want to try and do myself, seems pretty simple for what you guys say), will I need anything doing via VAGcom which I don't own or know much/anything about?! Cheers!
