Misleading BRouter message if road is unsealed
This is probably a BRouter issue but I thought I'd mention it here just in case. If the selected navigation profile has "Avoid unpaved" selected (as below), and the track being added IS on an unsealed road, then a misleading message is displayed that "from-position not mapped in existing datafile". This is incorrect. It is just that BRouter cannot compute a suitable route to avoid the unpaved road. It took a few experiments and fresh downloads of BRouter RD5 files to realize where the problem lay. If Locus has control over this error message then it could be improved.
