I have been experimenting with mkgmap and struck and issue with the search features on my Garmins. My 62s using the spell search will find items such as lakes and huts (I am a bushwalker) but my Rino 650 can only find cities under the point of interests. I am using the same img files created as per below Windows 7 bat file.
