What are the benefits to the F-series -> 3.0 update CNSD-100FM? If I am going to pay $120 dollars for it. I need to know it is worth it. Is the boot up time less? Touch screen button response any faster? Stop jumping to map when you get a BT phone call? Any other problems corrected? I have read many of the posts here but nothing listing the 3.0 update system improvements. If it is already listed plase post me the link. Thanks
