I recently bought an RNS-E and was going from the Symphony II with Bose to my new RNS-E.
It really was a doddle thanks to the Kufatec cables I ordered! No pin alterations reqired as they done all that for me when you state you have Bose.
I opted for positoning my GPS antenna above my clocks so took the dash out and stuck it with some double sided tape to the area above the clocks. Will have to see how my GPS signal strength goes, but so far so good.
Below are th cables from kufatec, i ddnt take pics of the install, as it really was so easy! Just plug and play!
Kufatec Harness Adaptor & Kufatec Diversity Antenna Adaptor:
After testing I have found that I do not get any noise/humming from my speakers like ive notced many others on his forum have complained about with their RNS-E installs?? So bit weird, but im not complaining LOL. Although when I did lock myself in my car to test this, the only sound I get is the spinning of the DVD for some time. But I beleive this is normal.
I also have my Ipod kit hookd up to the CD changer part of the RNS-E also, and that still works perfectly fine.
Oh and the DIS direction info displays first time without having to mess around with pressing the pins on the clocks or switching the engine or head unit or or off.
Also just wanted to say thanks to Mitch78 for a smooth transaction and sending of the RNS-E, Top bloke and would recommend to anyone else wanting to buy parts from him.
