SW 0200 or 0270
 

I'm kind of late to the party on the RSN-E installs and software changes but I just got my B7 A4 Cab about 6 weeks ago and have been enjoying it since. I have installed a RSN-E with SW 0020 installed, I would like to update to version 0200 as I would eventually like to install a backup camera. Any threads I have been able to find on 0200 are very old and most of the members involved are not active. I would appreciate if someone could give me a little direction on where to find a trusted version of 0200 or even better a version modified to 0270 so I can use the newer maps. I currently do not have a map DVD, even knowing for sure what version of maps would have 0200 would be helpful.
Thanks -
