I'm planning on taking a road trip soon and wanted to use my 3G iPad for navigation using just Google maps. Would having the Google maps on for 8 hours of driving blow through all my data quickly? Any experienced road trippers done this?

Could I get an initial lock with the 3G, turn off 3G and continue with just the aGPS to find my location on the Gooogle map?

    I am guessing you are using a 2GB monthly plan? I have used about 2.6GB of my monthly plan by streaming radio at work for the past week almost all day. I don't know about google maps, I don't imagine it should be eat through 2GB in 8hours. I would recommend keeping the zoom level the same so you can avoid map redrawing. Something you will have to keep in mind is that you will need some form of connection to draw the map, the blue dot might move but it has no map to see where you are might be a problem.

    Good point about the zoom factor regarding data use. I haven't initiated my 3G plan yet as I have only used the Wi-Fi connection so far.

    While the music streaming info helps, I'm assuming map graphics would use data quicker.

    I was planning on keeping the Google maps on 6-8 hours each day of a week long road trip so your data use of streaming audio is eye opening as far as the potential data use I might incur.

    Yeah, depending on zoom level you are using you will be loading images as needed instead of constantly pulling data which is what I am doing. I would have to do some baseline testing of this to compare the data used on each. Ah, if you purchased the iPad before the 7th of June you should call ASAP to see about an unlimited data if you are worried about running out of data.

    Just called ATT, no joy as far as unlimited plans go. I thought of spending the $20 to tether my iPhone to my iPad for data, but they said if I did that I'd lose my unlimited plan on my iPhone...

    If you purchased the iPad 3G before the 7th of June you are grandfathered into the plan. You cannot ask for it because they will say the do not offer it, you need to get an iPad support on the line and say you purchased before the cut-off date. You will gave to give them some info off the iPad and then they will ask you for when you got the iPad, purchase date, and once they verify that they will allow you to sign up for unlimited. Other than that I would say sign up for a 2GB plan, and if you go over expect to pay an additional ($10)? for another GB on that up to 5GB (I believe). As long as you have a little extra that you are prepared to spend on this trip then you should be fine.

    Thanks for the info! I purchased mine in May.

    For $49, you can get a full featured turn-by-turn navigator with on-board maps and voice guidance. Then you won't need data as you already have the maps.

    You have several misconceptions in your statement.

    First, unless you're driving along the Northeast corridor, you're not going to have 3G connections for the whole 8 hours. You're going to find some EDGE and some nothing, so you won't have any ability to navigate. I would never even consider this, unless I was driving in a city.

    Second, aGPS works only with a cellular connection. It stands for assisted GPS, which theoretically uses both the satellite and cell towers to get a better fix on your location. If you turn of 3G, you just get a GPS signal, which has been quite fast in my experience. Personally, I think aGPS is needed in cities or areas where one or more satellites are cut off from the line of sight.

    Third, once you turn off your 3G, you lose google maps. Period. Besides, I'm not sure I want you driving worrying about turning on and off 3G. That's dangerous.

    As several have mentioned, get a real navigation app on your iPad. There are literally a dozen, some good, some not so much. Then the maps are stored on your iPad.

    You had until July 15th to sign up for the unlimited plan... It' already the 16th.

    No worries, I'm not driving on this trip, I'm navigating. On past trips I've used Streets and Trips on a laptop. I wanted to simplify my gear this trip.
