Hankhan

Changes made from version 3.80 to 3.90: * Added German tide support. * Added support for extended resolution maps like Minnesota LakeMaster maps. * Improved Data Review page to show depth or height of structures like bridges on BlueChart maps. * Corrected track log filtering.

I like mine - great reception, color adds a lot to the useability. Lots of room for maps.

There are lots of discussions here on this topic - did you try a search? I have the 76CS, I had a 60CS when they first came out. I really like the expanded basemap in the 76 series - it's very useful to me.

Does anyone know how close they are to releasing a V7 Mapsource product?

After upgrading I got WAAS lockons for the first time.

I've had my 76CS almost a year and I've only used the basemap in the unit for auto-routing. It's worked great. I keep thinking about buying City Select, but haven't found anywhere where I need it.

The "Buy it now" price of $80 + $ shipping seems pretty high considering I can a new one from Amazon (with full functionality of two lock codes) for $107 and free shipping.

Do I have to do anything special to install it twice? I'd like to install it on my laptop and need to know if it'll work with both my Garmin GPS units. thanks..

Doesn't the 76 series have the same geocaching mode as the 60 series? I'd suggest you do a search for this topic, it's been discussed a lot here.

http://www.msnbc.msn.com/id/6720387/ WASHINGTON - President Bush has ordered plans for temporarily disabling the U.S. network of global positioning satellites during a national crisis to prevent terrorists from using the navigational technology, the White House said Wednesday. Any shutdown of the network inside the United States would come under only the most remarkable circumstances, said a Bush administration official who spoke to a small group of reporters at the White House on condition of anonymity. The GPS system is vital to commercial aviation and marine shipping. The president also instructed the Defense Department to develop plans to disable, in certain areas, an enemy’s access to the U.S. navigational satellites and to similar systems operated by others. The European Union is developing a $4.8 billion satellite navigation program called Galileo. 'Clearly a big deal' The military increasingly uses GPS technology to move troops across large areas and direct bombs and missiles. Any government-ordered shutdown or jamming of the GPS satellites would be done in ways to limit disruptions to navigation and related systems outside the affected area, the White House said. “This is not something you would do lightly,” said James A. Lewis, director of technology policy for the Washington-based Center for Strategic and International Studies. “It’s clearly a big deal. You have to give them credit for being so open about what they’re going to do.” President Clinton abandoned the practice in May 2000 of deliberately degrading the accuracy of civilian navigation signals, a technique known as “selective availability.” The White House said it will not reinstate that practice, but said the president could decide to disable parts of the network for national security purposes. Part of space policy The directives to the Defense Department and the Homeland Security Department were part of a space policy that Bush signed this month. It designates the GPS network as a critical infrastructure for the U.S. government. Part of the new policy is classified; other parts were disclosed Wednesday. The White House said the policies were aimed at improving the stability and performance of the U.S. navigation system, which Bush pledged will continue to be made available for free. The U.S. network comprises more than two dozen satellites that act as beacons, sending location-specific radio signals that are recognized by devices popular with motorists, hikers, pilots and sailors. Bush also said the government will make the network signals more resistant to deliberate or inadvertent jamming.

I'm not using an external antenna with my 76CS - and I use it a lot under the heavy tree cover of Northern Idaho and the only time I've lost signal is when I put in my pack and gets sideways. I used in the car in the cup holders and it keeps lock there too.

I have the 76CS and the basemap is good enough for me to do all my autorouting on. I had the 60cs on order and canceled it when the 76CS with twice the memory came out for only $35 more.

2x the memory is a big difference, but for me the batteries sitting horizontal has been a real help. I don't use my 76cs on the water (never have) but I do use it on my quad and cycle in a ram mount and it has never shut down due to the batteries losing contact.

It's a fairly well-documented Garmin thing. See, Garmin's have their batteries mounted vertically, so any up-and-down motion tends to pull the batteries away from the contacts for a fraction of a second. Jamie My 76CS has it's batteries mounted horizontally, I've used it on my quad and cycles with no problems.

I bought some Palm PDA screen protectors off EBay - got a dozen of them for $1.50. I checked out the same thing at one of those chain office supply stores and they wanted $16 for the package. Works great. My 76CS really takes a beating in the Idaho woods, I've taken some nasty spills while holding it already. I've got the 60C/76C template for cutting them to size if anyone needs it.

Garmin GPSMAP 76CS - recently upgraded from a Garmin II+. Big change.

I've tried my 76CS under heavy tree cover - where I couldn't see sky - and it worked great. Never lost signal.

I've had the 76CS since it came out - I've auto-routed everywhere I've wanted to go using the basemap, it's pretty good. I'll buy City Select when I find I need it, so far I haven't. I keep all of Idaho/W. Montana and E. Washington TOPO maps loaded, they use less than 1/2 the memory.

Mine has done this once, similar cirmcumstances - I'd been driving for about 3 hours, using the basemap. I picked it up to fool around with it and it was stuck. I had to power it off/on to get it to respond. I was not on the most recent firmware (3.50).

I used my 76CS under some very heavy tree cover this weekend (N Idaho) and it never lost lock. I was sure it would, some of the places I was wandering around in were dark because of the cover. I autoroute using the basemap on mine. So far it's worked very well for what I want to do with it.

I use USB with EasyGPS - works good.

I download the waypoints I want to my computer, and then use EasyGPS to get them into the 76CS. Works very good. Please note, I'm not very experienced with the GPS and have no idea if what I'm doing is "correct".

I considered selling my recently purchased 76CS and getting the Quest - until I saw the battery. I'll stick with my AA's...

There are a couple of good threads discussing this here - the last one below has pointers to more threads on this topic. One of them (I think the first) makes a reference to the better basemap in the 76 series vs. the 60's. http://forums.Groundspeak.com/GC/index.php?showtopic=76344 http://forums.Groundspeak.com/GC/index.php?showtopic=74667 http://forums.Groundspeak.com/GC/index.php?showtopic=75375

An example is the TOPO maps for N. Idaho don't show a road I had built 4 years ago into some property I have. City Select has the road and it's named too! Pretty amazing for a little, one lane gravel road.
