Pioneer has Firmware Update for AVIC F-Series Navigators
Pioneer's AVIC F-Series navigators aren't exactly problem free, and with the Internet, it is pretty to read all the angsty comments and problems that crop up. Good thing Pioneer has the presence of mind to whip up a free firmware update that targets the US-based AVIC-F90BT, AVIC-F900BT and AVIC-F700BT. The update is said to "improve overall system performance and resolve certain software issues." While the AVIC-F500BT does not require any upgrade, it is still advisable to apply the firmware update just to be on the safe side. Well, I would heed such advice from the manufacturer as it can't get any worse, can it?
