Right guys. Think i've made the decision to upgrade my symphony 2 (think its a 2) to the RNS/E. Now i've read the sticky on retro fitting it, sounds fairly straight forward if you already have the symphony 2. I have a few questions i hope you guys can answer -I have Bose...will this be effected?? -will my factory Bluetooth/phone prep be effected?? -Will i still need to buy a connects2 or similar to connect my ipod - Any problems arrise with the drivers info system? -Best place to get additional cables (if any required)? -Any other tips or pit falls to be aware of during the fitting? Thanks guys, and sorry if i've duplicated another question, i searched the best i could.
