Hi caty...I would like to site regarding this issue...you only need to use the sn of the SD card to generate the code.. copy it into unl file, copy the Foder`s gpi file into device Poi folder..or SC card Poi folder (only one folder)...that`s it .
On nuvi device go to Where To ..then Extra ...you will see the Foder`s Travel Guide... ( tested on nuvi 760)
But unfortunatly it's limited to very large cities only ...unimpressed.
