I have now sourced erverything I need to install the RNS-E into my 2005 A3 8P Sportback. (Single to Double DIN convertion required). i have not purchased the double DIN climate control as it is way too expensive. I intend to modify my existing one. I have registered on the navplus.us website but cannot login untill I receive an email from them and they haven't sent one after 4 days! I've tried emailing the webmaster but still nothing. If anyone is a member on the site can they post a question for me as when I log in all I get is a message 'Name pending registration'. I need someone to activate my login! The main reason I want access to the navplus.us forum is to see if anyone hase a template for the required size of the double din climate. I'm sure that there are many people on here who have done the same conversion so someone must have made a template ?? If so, do you want to share it with us all. I read a post somewhere that said you had to measure 5mm each side at the top and 3mm each side at the bottom, join the marks with a straigt line and remove the excess. I'm sure this was for an A4 but maybe the same is required for the A3? Can anyone help.......please.
