I thought I could help out and share the August 2013 v50 upgrade for the 430N (RHB).
I received my disc in the mail last week and decided to make an ISO for the Jeep and Ram community.

I have a 2012 Ram Sport with the 430N and received the incorrect disc in the mail which downgraded my system from v43 to v33 with the ugly blue backgrounds. Many searches and calls to Uconnect later I got the disc and all is good!
