Hey guys, I'll be browsing the web on and off today for answers to these questions and posting them back here, but if anyone has any insight to share I (and I'm sure others) would greatly appreciate them! 1) RNS-E firmware updates. Installation, new firmware with older units, which is the best one out atm, etc. 2) RNS-E chrome dials! For those who don't want to shell out for a new unit, how to get and install them. 3) RNS-E + BT loom. Audi part number, and recommendations for a custom splice. I've searched around and only found mention of the above, no specific Q&A. So, will browse the interwebs and return with what I find. Thanks in advance for any help guys!
