I downloaded the firmware 2.0060 from pioneer, Do you think this is the way to solve the problem? (By inserting SD card to install )?

I got a AVIC-F900BT, it is not not longer picking up GPS signal(go into setting page for GPS navi, a Red 'N 'is showing and no strength showing up. , have not said that i have been using for 1 year with no problem and did not remove the deck or any hardware. GPS not working since i connect the unit with my iphone 4 for a few days and the whole unit just keep re-booting(can not get into menu pageï¼ï¼‰but after a few days, it can into menu page but GPS is not working. Any one knows what happen??
