On my former '08 RL my home address was not in the data base. It gave me my next door neighbor to the south. On the '08 RDX it is, but when I set it it says it is 400 feet away. I tried to correct the position (the manual did not advise using this feature), but it is screwed up now. Can I disconnect the battery and have the Navi reset to the default? Do I also have to remove the DVD too? Any info will be greatly appreciated.
