Cache Downloads in How do I...? Posted July 14, 2008 · Edited July 14, 2008 by lrosell Hello all, Is there a limit to the number of caches that I can download to my Garmin nuvi 750? I have a 2 gig card installed updated software and 2009 maps. I'm on the road often and unfortunately I am not able to install the plug and play software on my company owned laptop, so I download a bunch of caches at home for when I am on the road. Thanks Allen Usually the Nuvi won't hold more than 500 caches which is also the max size of a pocket query.
