I"m a newb to the forum so please forgive my lack of AVIC knowledge haha
What are the differences between the X910Bt and the F90BT? Is the X-Series worth the extra money? Is the X-Series firmware faster? In what ways, if any, is the X-Series worth the extra money over the F-Series? Which one should I get (I don't really mind paying an extra hundred dollars or so for the X90BT), or, which one is better to get?
Thanks!
