Avic x910bt head unit continues to reboot at splash screen , tried firmware update but since it never actually boots it won't read the SD card , please help

Try buying a cleaning disk to clean the head.

Download frsh firmware from manufacturer, yours may be corrupt and use a NEW sd card, they do develop faults every now and then

What is the matter with these 'Expert' jerks posting the same stupid solution 'hard reset'. First off, the hard reset instructions are wrong: YOU CANNOT REMOVE THE BATTERY FOR THE 1000 SERIES Nuvi's!. Second, most of these people are telling you that they CAN'T get into the files through USB.

There is a way to get into a 'pre-boot' mode by holding the upper-left of the screen, then plugging into the USB. The PC then does recognize the device as a 'gps' device.
Problem though:
1. It doesn't stay in this mode long enough for WebUpdater to properly re-program the device.
2. One of Garmin's support recommendations was to delete 'GPUPDATE.GSD' from .system (actually they say 'Garmin' folder, but the 1000 series moves these files to .system) but what they fail to realize is that in pre-boot mode, the PC does not see this as a mass storage device.
3. So what we REALLY need is a utility that will let us manipulate the files in pre-boot mode, and the right files (READ: Firmware files) that we can download first then use the utility to install. There is such a utility AND firmware download for the 600 series, but not the 1000 series that I am aware of.

Try the newest firmware update using a SD card http://www.pioneerelectronics.com/PUSA/Support/CarAudioVideo/In-Dash/GPS-Navigation-Systems/ci.AVIC-F90BT.Support?tab=B

"Check serial Input" is just part of the cycle on boot up. It checks for a key press on boot up so that it can access a hidden menu. A cradle, serial null modem cable and hyper-terminal is required to bring up this menu

You can try and re-install the operating system.

Download the latest image from Intermec (you will need to register) and then load the image onto an SD card.

Remove the front cover just above the scan engine; 2 slot head screws and insert the SD card. Cold boot the device. Take off battery and hit the reset button a few times. Re-install battery.

Image will begin to reload.

Detailed instructions are available with the download.

NOTE: The latest image downloads from Intermec not longer have the Telnet application pre-installed. If you require the telnet client then select a previous version, but then also not that there are usually 2 versions EX25 and non-EX25 scan engine type.

Have you tried updating the firmware? A new version is available from the Pioneer website. You will need a blank, formatted SD card. Unzip the files from the Pioneer download and copy to the SD card. With the key out of the ignition put the SD card into the unit. Put the key in the ignition and turn to position I to turn on the F700BT. The update takes around 10-15 minutes. Ensure that no unnecessary electrical accessories are on in order to save battery life.

If that fails you may wish to check out www.avic411.com.

put the pics on an SD card , go to the splash screen and transfer them over.

have you upgraded the firmware on this unit ?
his firmware update (version 2.0) contains important performance improvements relating to, among other things, boot-up time, Bluetooth connectivity (including certain Blackberry models), iPod Touch (v2.0) compatibility, touch screen response, display brightness, and SD and USB media playback.

try getting the new 2.0 firmware on and put it on a SD card, install the new firmware and then install AVIC feeder on ur computer and change the settings to your likeness and save it on ur SD card. your AVIC will ask you to update aka yes or no and click yes, after the first time it will restart and load again with the same ?, click no and go to MSN direct status. keep in mind that the upgrade must take place in the cradle in a msn direct zone.

try to press the reset button on the left side next to the usb port with a small paper clip or toothpick and see what happens and see if it did is firmware update,if not do it over and the unit plugged in with powersupply and the usb and leave it alone and let it reset a few times until it says to unplug from the usb .for the sd card make sure is a flash sd card.i have a mastreo 4000 with a 2gb sd flashcard and it has no problem.theses units has unlimited amount of any size of gb sd flash card.let me know what happens.
