Maybe while you're 'finding your feet' here again you might like to use the image version [see the link in the post above yours]. BaseCamp can also use images [even locked ones] on a unit, media card or usb drive. Best don't use MapSource with modern installed gmap topo maps [or CNs] it's not designed to cope, BaseCamp/MapInstall is best used for the PC version particularly for generating images.

All the info you need to catch up is here: [Only registered and activated users can see links. ]. For ActiveRouting db files, pay attention to these threads from the index: [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ]. For the 'other type' db files, look here: [Only registered and activated users can see links. ].

You question about JM for unlocking vs. 'something better' [i.e. using another type of unlocker] can also be answered by checking the Tutorials index.

If you need further clarification at all, please post in one of the appropriate threads linked above or another from the Tuts index.
