But once the pq is on the gpsr, you can always select GO and go geocaching, the only thing is that you don't have the description and the logs if there is no data/wifi connection.
I went out geocaching yesterday but something went wrong and the gpx was not on the gpsr, lucky to have live geocaching on the gpsr
And the smartphone stays in my pocket, the mails and sms are shown and are fully redable on the gpsr.
