Sorry for the later response, but it took some time until I got feedback
from the reporters of the problem about my changes to fix it.

The reason is: with very old Garmin devices, you should not modify 
the background as this could have lead to problems.
With some new devices, you have to modify the background, means
you need a polygone 0x04b with draworder 1, and only this polygone
with this draw order.
