Good info.
I'm good to go.

Thanks for the USB research. It's good to know you have it as a option (slow one). I'll see how Garmin support  goes and report. It sounds like it's not going to be an issue. Either way it's no big deal. I'm plenty happy with the data I have and have yet to have a problem finding what I need around where I live.

Nice on the 750 tips. I tried it today and panned around the state last night. I guess I got a little spooked being in the city and not seeing any elevation. Its pretty flat on the drive in, so its not shocking. Has anyone tried this unit by foot? The battery specs are ~5 hours. I'll have to look around again for charging. I'm trying to remember if you can charge right out of a usb 12V car charger if you don't have the vehicle mount on you trip. Here is another curve ball for anyone interested. When I hooked up the gps for the first time I believe Garmin offerd a free annual upgrade on new US map changes. Online the southwest and the southeast was backwards on Garmins website. I clicked on the one I though was correct for the southwest but it gave me the southeast. I think annual updates are fine for me and was wondering if you called Garmin tech support they can revearse it? Anyone had similiar problem?

Like usual it's user error but I still don't know whats wrong. If you put the detail on the highest setting and move out of the city like Globe area the topo will come on but at lower detail it flashes for a moment and goes to a blank color. There must be to much data in the city? I guess I need to play with the detail and the unit more. The good thing the topo maps are in there.

Thanks for the new map info. I have to ask a question. When I last left this forum I went and loaded some other state maps and anything in Arizona I missed. Iwas driving into work this morning and was hoping to see some elevation and new things I hadn't seen before. I took the view out of 3-D(normally drive like this) and set to track up. The other is track North. I seem to have donee soething that stoped the topo from working. I tried AZ topo only with basmap and nothing. Went back to turn on all around 5 maps and nothing. i think i tried every AZ map and nothing. Did I do something obvious of do I have to reload maybe just AZ topo. Thats all I really need but was playing around with like HI, MN, Southwest. Any ideas? Can I delete the maps from the unit easy and try again. Chad

Got it. I'm very happy with the 750 for now. It sounds like the better or newer models have a little way to go still. But that never changes. I get detailed enough topo images for my needs. Bigger screens are always nice but this is still a vehicle unit which in my opinion must have a balance of size, portability, and mounting. Again, great site and I'll try to return the favor someday.

You can install one additional map in internal memory, and a second one on your data card. The files  will each be named gmapsupp.img. Starting with the 1200/1300/1400/1600 series, Garmin did away with map filename restrictions, so you can add as many map files as you want on these Nuvi's and call them anything you like.

I must be running on half brain this morning. Does this mean
gmapsupp.img for all of these 1200/1300/1400/1600 series?

Open the files and save under gmapssupp.img as one>

Do I get the files at Garmin? Sorry, a little confused.

Thank you. Good information. I will work on it today.

I found out what I was doing wrong in Mapsorce loading maps to device SD card. I choose drive letter (F:Removable Drive) that the was in the pull down tab. I'm loading a South West map which is rather large (1G+) and it will take some time. Hopfully all goes well. It's interesting. I un-checked all maps in the maps viewable screen in the Nuvi 750 and it still had road maps in it. There must be some internal ROM inside the unit loaded at Garmin? This is really cool. For years I have had to bring a labtop on excursions around our beautiful state. The portable Rhino has a small screen (no color) which is like watching a movie on a 2" screen. Years ago I used to go with Microsoft Streeta & Maps, Mapsource, and Mapsource with the Rhino all at once. The labtop is still great for larger viewing areas for yourself and 2 people. I'm sure there are several tricks to the trade as I go but this is again is really cool. GPS Depot kicks butt!

I have a 4 GB memory card. It seems that its a independent drive. I read it fine on the computer but it doesn't seem to extend the system storage  capacity for more maps? I have been trying to figure it out for about an hour or so. Re-format sd-card? Thanks for the input. So run 1 type of map type at a time but overlays are OK? Chad

WOW that was easy! Do you no if it's ok to run multiple maps? Maybe AZ topo, US streets (forgot name, came pre-installed in Nuvi). Is there a limit? I would guess to much data? Any experiences good or bad running multiple maps at the same time?
Thanks, Chad

Thanks, I will start reading. Thanks for the quick response! Gives me something to do tomorrow.
