WorldNav 7100 Firmware Update

GPS Postion Fix Updater

Some of the 7" model GPSs beginning with serial numbers LS7100-0309... may be experiencing difficulty locking into position today. We understand that the government has made a change in the satellite communication structure which is affecting some of our GPS devices. Rest assured, your device is still functional, you will simply need to update the firmware in order for the device to recognize the new satellites.

Before you attempt to update your device you will need to obtain a 1 or 2 gig SD memory card. If you do not have a blank card then contact TeleType to receive a free updater card. If you want to try to use your existing WorldNav memory card call TeleType for assistance as you may wipe out your navigation system if you are not careful. Customer Service toll free 1-800-717-4478.

If you prefer to have an updater card sent to you, please register your device here:
