I Phone-MB's needed for Navigation app

I would get a map. That's what we use in Scotland.

What kind of navigating do you want to do - - walking? driving? It's going to make a difference.

Which navigation app do you intend to use? Only then can we maybe come up with a guess. What will you use it for? If you are speaking of Google Maps or Apple Maps expect to have to leave data on and have a big bank balance to pay for the mega bill when you get home. There are ways around the problem but we will need to know more. Are you driving? Walking? Hiking? FWIW I use a very good nav app that doesn't use any data at all. Its not perfect but pretty darn good. And free.

My apologies as I wasn't very clear. I plan to use it on rare occasion while driving. The crucial time will be leaving EDI as I will be driving the first part of my journey by myself which is why I would like an app to give directions. I drove out of there before but with someone to help which made it much easier. I currently have an AT&T Navigation app, which is what came with my phone. Whatever will get me first 15 minutes from EDI and past the first few turns to the highway is my main concern and again in Glasgow. AT&T sells chunks of data but I had no idea how much I could possibly go through. Nigel, if you have other suggestions, I am happy to hear them!
Thank you!

Get NavFree. Download the maps you'll need before you leave. You won't need a data connection to use them, so don't buy any. Watch your battery usage if you keep it running very long - - better yet, take a USB connector for the lighter socket. Nigel's gone to bed, but he clued me in on the above - - every once in a while he shows a lick of sense. Keep cellular data turned off the whole time you're gone. Wifi will kick in automatically, you'll still have a phone and gps. If you screw with the airplane mode on the plane, switch it back off when you land or you'll have a mess trying to unscramble things individually. Take it easy going out of Turnhouse, the roads are a mess due to all the construction. Remember that those are TravelEx atms on the arrivals level, but if you run up to the departures level, there's a bunch of bank machines around the corner from the Nero coffee place.

Hi Ed, That's great! I am dowloading the UK version. You just saved me from purchasing unneccessary data and I really appreciate it. I will toast you when I get to my cottage! Since it sounds like you were there recently, and if you don't mind answering one more question, what hotel do you recommend for the night before my flight back to the US? I would love to be about 5 minutes away.
Thanks!

ummmm..... errrrr......well..... Since most of my Scotland/Wales trips are running around in the mud looking for standing stones and hiking.........and my adult leader won't have a part of either...... ......and since I'm cheap....... .....what I do is drop the car after supper and conk out in the airport waiting for the dawn flight..... Send me a magic marker and I'll put your name on a chair.

I hate to rain on the NavFree parade, but I tried it two weeks ago and didn't care for the way it worked. I have the TomTom app and like it better. It works off line as well. It works all right, but I find it a bit clunky compared to the Google Maps app. GMaps needs data though. If you can get the 4s unlocked, prepaid data is cheap in the UK.

NavFree isn't perfect, and the POI interface is slightly - ever so slightly - dodgy, but it gives the same directions as my super duper Garmin, faster and with more local roads shown at speed. The price is pretty good - free - and it doesn't use any data after the initial download which you should do where you have good internet, like at home; it doesn't freeze up and the pinch to zoom works well. In my rating for it I gave it *****.

I spent a bit more than two weeks driving around the western highlands in October of last year, with an iPad using wifi. Except for one location (a B&B mistake), signal strength was at least acceptable, if not speedy, every place I stopped overnight. Ditto places I stopped along the way. On the road out in the boonies? Not so much. I have a 4s with AT&T. I would make sure wifi is enabled in Settings. Then, at the bottom of the wifi screen, there's on option to "Ask to join networks". Set to "off", it joins networks automatically, unless you need to enter a username and password. If "on" it prompts you first. Most of the wifi I found on my trip required a username/password combination from the B&B, hotel, etc., so I just kept it at "off". Data roaming: Yes, turn it off. On the plane before you depart, when you shut the phone down, is a good time to do it.

I just downloaded the Italy version of Nav Free, and will give it a test during my next trip. When I first had a look at it, the App seemed to want to access the net for location data, so I'm wondering how well it will work in off-line mode? The Nav Free firm's webpage has some information on the topic, but I'll look at it later when I have more time. If anyone is interested in the comments regarding off-line use, have a look at Answer #1: http://www.navmii.com/support/faq Cheers!

buy a country-specific TomTom app for your smartphone. It will work offline (no cell data traffic) and it is cheaper than any MBs you might need.
