Unlocked. Otherwise your unit will freeze during Navigation (it needs the free space on the SD Card to run DATA)

Application error.

This is not an uncommon error and is mostly referred back to Nab=vman for repair

Other than sending it to Navman you can...Open up the unit (this voids any and all warranties you may still have and if you go with this option forget about contacting Navman). F20's internal flash is just a hidden micro SD card. If you don't have it already, you'll need to get a cheap micro SD card adapter -- with it you will be able to read the card with any card reader. You could then scan card for errors and look for log files that could provide more information on what went wrong with your unit.

try to press and hold the power button for 10 seconds then release and check if you can replace the battery or if the unit is still under warranty try to call their support if they can replace the unit if the unit is still under warranty.

Garmin Golflogix GPS-8 New unit, new batteries, unit won't turn on after hold power switch.

If you downloaded the new software on a mac it doesn't work. You call the company and will receive a new device, then send the bad one back. They take care of shipping.

My sanyo nvm 4370 video option say no video player installed

This unit only supports MPEG4/H.264 file. The files format has to be .MP4. This unit cannot play all MPEG4/H.264 movie files. Most movies out there are converted using DivX or XviD codec so if you need to convert them to this supported format. It will mostly cost you time if you found a free converter.

If you don't have time. You might try my basic hack to add a 3rd party media player that will play almost everything out there and it also supports sub-titles. You can check out my video on YT @

This problem can have several causes.
  1. A component fault on the units internal antenna circuit board.
  2. ribbon cable has become detatched inside that connects antenna board with main circuit board.
  3. A software fault.
  4. A component fault on the processor board.
All the above except number 3 will require proffessional investigation. if its a software fault then you may be able to recover data by a re-install through TomTom Home or by recovery backup ( you did make a backup of your SD card , didn't you ? ) of your SD card.

If the unit is still under warranty, send it back to Tomtom. Even if the unit is no longer under warranty, complain to Tomtom. There is a problem with the CLA (cigarette lighter adapter). It can cause internal damages to your Tomtom. What happens is that there are three wires in the CLA along with a voltage stepdown circuit board. The wire are +, -, and a signal wire. If the signal wire get disconnect the voltage could spike up to 12vdc. The unit is designed for only 5vdc.

If the unit is out of warranty then try the following website for repairs. They can fix the two chips which usually blows.

No signal

There are three forms of resets on the unit.

The first is the reset under the front face plate. The second is where you hold the power button for a long time (30 seconds).

The last and potentially warranty voiding solution is to pull off the front face plate. Remove the four tiny philips head screws. The front face plate can now be lifted off. There you will see a battery and a little connector with 2 or 3 wires attached to it. Disconnect it. Wait a while... 30 seconds.... 30 minutes... overnight.... and plug it back in.

I've read some reports about the web updater software flaking out, so I recommend flashing through the SD card slot if possible.
