When I dowload new maps the existing ones disappear?

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 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.
