Although bug #730 (DTM on French
BSB charts) has been reported to be corrected in the previous beta, a French user has reported (and I have checked) that there is a still a large discrepancy in charted positions between the 2.5.0 version and the
current beta. This is best seen when overlaying with GE using Higgins' GE2KAP.
Here is the header for this example
