I had one switch off and one freeze that required a reboot, both during navigation with OSM loaded.
I then moved to Garmin NT (USA and Europe, on separate cards) and have had no issues since.
Only caveat is that I suspect the sample size is a bit small to prove the point, but anecdotally the official maps seem to fix the issue.
I bought the USA map as a download - would not do that again as it was a massive ball-ache, the download took forever over a 100 Mbps line. It was like dial-up.
Europe maps I got on the Micro-SD card, significantly more convenient.
