Has anyone tried loading custom POIs into the Garmn nav in a 430N (RHB) media center? I followed the instructions in the radio book exactly but have had no success. The Garmin POI Loader (from the Garmin web site) works as it is supposed to for creating the poi.gpi file. I know the file is good because I have successfully loaded it into my Garmin nuvi 660. However, when I burn the file to a disc and load it into the 430N in my Grand Cherokee Limited, the disc reads and then the screen displays "PND Updated Failed" and the custom POIs do not load. I have a query into both Garmin and Jeep customer service but no responses yet. Just curious to see if any other owners have tried this.
