Using Multiple handheld GPS units with Topo 7, or 9

[+BFPierce]

Hi there, i have been using Topo 7 an d Topo 9 for some time now, but I was wondering if anyone has experience using multiple units with the software. It seems the software is tied to one unit, and I have accumulated now four PN-20's and one PN-40 in my family.. I would like to be able to put the full maps on all of them but when I transfer it over the unit says it cannot read the file...

 

I can easily use GSAK to move coordinates to the units, but as far as having anything more than the base maps I'm outtah luck...

 

Any help would be appreciated,

I don't believe Topo 7 maps are tied to one GPS. I own 3 PN-40s, and I know I have successfully transferred maps to two of the units from the same Topo install. 

 

I can't speak for Topo 9, so I don't know if they changed all of this for version 9.

 

FYI, try following this guide:

I have a PN-40, PN-60 and PN-60w all using the same Topo 9 mapping software but loaded on to individual SD cards.  I don't have any mapping software loaded in "Internal Memory".
