While I didn't get a great many RTL trap errors with the firmware, I ended up encountering another issue related to the 5.70 firmware that only appeared in the last couple days. When not navigating and zoomed in to maximum, the screen is slow to redraw at highway speeds. In fact the screen is so slow that the road will disappear off the bottom of the screen and leave me floating in space for some seconds before the road reappears. Both times the slow screen redraws were accompanied by a RTL trap error, so I reverted to 5.40 for the time being. Even if the slow screen redraw and RTL trap errors are merely a coincidence, I would rather sacrifice the icons for my favorites in favor of a properly functioning GPS. For me, the icons not appearing on my screen for my favorites was never a major issue to begin with and the fact 5.70 fixed the favorites bug was a nicety, but 5.70 has introduced new bugs that I hope Garmin has been notified about.
