Thread: Garmin DriveAssist 50 LM crashes and reboots at specific GPS locations

I'm now suspecting there is a minor hardware fault. Likely the BT controller is failing and if so there is no software solution. It may not worsen, or the problem may eventually progress to other more essential parts of the chip resulting in a total failure.

@Butters and @Boki_Srb, an update on my ongoing problem

I tried loading a copy of the latest map (MENA 2022.2) onto another area of the device filesystem using MapInstall. Whilst it did copy across to both internal memory and sdcard, I was unable get this to show on the device (under MyMaps) and therefore, unable to select for use.

I had an older 2019 Middle East and North Africa map downloaded and was able to select this and extract only the area I wanted (UAE) using MapInstall. On the device (MyMaps), I was able to select this newly extracted map whilst deselecting the main maps (2022.2 MENA and 2022.2 FourSquare) from active use.

On day one, I left Bluetooth disabled and had no problems whatsoever.

On day two, I enabled Bluetooth and have been driving for two days now with no crashes or any problems.

Overall, this workaround seems to be reliable, suggesting this is a memory related problem.

I have a couple of questions and hoping you can advise.

1. The main maps don’t appear in the ‘visible’ filesystem and there appears to be no method of downgrading these to an earlier revision using MapInstall, or Garmin Express. Is it possible to rename these files with an alternative suffix (.old) so they continue to occupy the defective memory, whilst allowing me to have the latest map in a separate area?

2. Is there a reason why there are two maps MENA and Foursquare?

Many thanks again for your continued support.
