Are you using the Singapore SLA map when you observed the speed limit? There are only certain roads with speed limit when you switched to MFM-Galactio 120630, whereas the Singapore SLA map will show you more details but it only has the coverage of Singapore
I just got my Holux 62S-AV. I have updated to the firmware and the map from Galactio website. Now I have also updated with MFM-Galactio 120630. During driving, I noticed that the navigation map when using the MFM-Galactio 120630 does not give the speed limit along the road as compared to the map provided by Galactio. Is this correct behavior?
