When I dowload new maps the existing ones disappear?
« on: February 09, 2011, 02:56:46 AM »
Hi everyone.

I have detailed topo maps installed on my Garmin 60cx, but when I go to add MyTrails to the unit I can't find the existing maps any longer? The trails display, but the detailed topo's are gone. What gives with that. When I look under info they're not listed there either. Do existing maps get deleted when new maps are added??

This is frustrating.

Thanks for any insight!

As this tutorial http://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/ mentions in step 8, you need to send all the data at one time.  If you have a newer unit, i.e. CO, OR, DK, 78, 62 you can rename the gmapsupp.img file to 'somename'.img.  Other units will only recognize a gmapsupp.img file name - for those units you will need to rebuild/resend everything at once each time you add/delete a quad/tile/segment from a mapset(s).

That explains a lot.


I thank you for your help. I was racking my brain trying to figure that out. I'll just send it all at one time then.

Thanks.
