Garmin 7×5 Devices Spontaneously Bricking
Overnight we started receiving numerous reports from Garmin 7×5 users that their devices suddenly showed a firmware update on screen. Often this was in the middle of a drive and not while the device was connected to their computer. Users who allowed the update to happen have been greeted by a host of unpleasantries– from their devices completely dropping satellite connections to the unit becoming bricked.
We can’t help but notice the similarity between this issue and the recent failure of Omnitech GPS devices although it is very possible the two issues are unrelated. In that case the chipset firmware failed to take into account a pre-announced change in time formats from the satellites. Again, this could be completely different, but it does appear to be chipset related. Garmin Support folks currently don’t know what is up and are issuing RMA numbers to have customers return their devices. Our advice is to hold off before going through with that as a software fix seems plausible. However please do still call Garmin Support to report your error.
There is a long thread about this issue in our discussion forums. If this has happened to you, please go there and report your issue.
