Sorry, all I can append is - Yesterday I upgraded to SU-18_2006SE_2.2006.39-14_PR_F5_MR0_ARM.bin and I use the modded Maemo Mapper 1.1 that has the twin Maps loading capability ( Topology or Streets) and this works fine with my Rikaline Bluetooth GPS I loaded the Mapper 1.2 also and got it working, but decided to unistall it as I currently have a need to toggle between Topogy and Street maps.
