I had downloaded and install the MFM-Garmin 091130 into my nuvi200. Notice that the postal codes search not found to most of the industrial/ Commercials area... not much problem searching for HDB area though.. was it due to presently, the map had 17,000 postal codes with mostly are residential areas? Need to run most to commercials/ industrials areas for meetings but always postal codes not found. Will purchasing of SLA-MFM solve my problem? Pls advice thanks!
