Hmmm, not sure if my GPS has those features. I'll have to dig a little deeper in the owners manual, I guess.Steve,
On my Garmin 765t, you can adjust the mix of the "MEDIA" level and the "navigation" level, there is also a "master" level. Perhaps the navigation level is turned down low.
If all you are doing is upgrading your maps you don't need a SD card. You can buy the lifetime updates and when you do so you'll get a registration number that is maintained by Garmin. I just updated my Nuvi 760 and it connected to my computer, I ran the software update and it automagically sync'd my Nuvi with the Garmin servers, verified I was eligible for the newer maps, and installed them. Be forewarned that it takes a long time to do an update. I had it running while watching a movie and it took all of two hours. The maps are large, so takes a while to download, and as long to install.I have a gift card for Amazon, thinking of buying the lifetime updates for my 350 nuvi.
Any thoughts on the matter and was wondering how big of a SD card should i buy for the upgrade, or if I need to buy a SD card.
