Hey guys, newbie question here. I have searched the forum but cant seem to find a clear answer.

I am working out which options i am going to order with my new roc. $2500 for the nav seems pretty pricey. I have seen RNS units going for around $1000 with sat nav. Just wanted to hear some opinions on how easy the sat nav antenna is to install, and if anyone has a trusted source to purchase the units, or should i just pay the extra cash to get factory fitted.

Your experience will be much appreciated.
