Not much, apparentley - this might be useful to you? https://ting.com/blog/how-much-data-does-google-maps-use/
Reading this thread with interest. I have TomTom too and looking at an in helmet headset - any recommendations with regard to ease of connectivity (not my forte) and value/reliability?
I think the main point for me is that while riding in areas where there's no network for mobile phone reception, which happens quite regularly. I use an old Garmin 500 which I can rely on. Was thinking about a new one though, think some have worldwide mapping too.
Maps.me on your phone. You can download maps for the area you want so no network coverage needed. I’ve used it in Italy and Spain and it was great
I’ve got the Zumo 550 which is on its last legs now. I uploaded European maps last year and it couldn’t find most of the places, yet my mates later model Garmin worked perfectly. I had to Tavel 15 miles outside of Kraków before it would pick up a road. It’s also very slow now, since I added the maps. Another thing, since I updated my uk maps, it tells me to make a left turn at islands, regardless of which junction I need to come off. I now have to look at the map at see which exit I need to take, which is very annoying and sometimes dangerous, especially when traveling at speed! I was gonna go for the 595lm, but may reconsider, after reading about the screen viewing problem
Google maps on your phone is great to get you where you want to go in the shortest / fastest way. Just remember phones do not like water. Even the best phone holders don't keep the liquid sunshine out all day long. When you stop you have to take the phone out of the case, water gets in. To take any photo's, you have to have a camera with you. I did the phone thing for years and swore by it. But..................... then I got a Garmin from Lidl for £100 and would never, ever, ever (ever) go back to the phone. Best thing about dedicated sat-nav is the ability to sit down in advance and plot all your favourite / new roads. This bollox about the adventure of being lost !!! Feck that for a game of soldiers. If I'm out all day, I have plotted a mileage to get the most from that day, be it 200 or 250 miles, not to spend my time going up some goat track and having to turn around. TomTom vs Garmin - if the're the same price, go TomTom, but if you can (and more likely to) find a bargain Garmin, there nearly as good. AndyC1 has a kick-ass TomTom, but to be honest, even being pretty tech savvy, he loses me when he's showing me stuff on it. Garmin - cheaper and simpler TomTom - better interface, but more expensive Then just learn to use MyRouteApp.com to plot routes and download - tutorials are available. I managed to teach one of the old codgers on here how to use it (no names).
I bought an Interphone case for my iPhone X and it’s completely waterproof, with rubber seals all round and you don’t have to take it out of the case to use it or use the camera. You can even charge it while in the case. The Face ID still works too (not with a helmet on though ) It wasn’t cheap though at £45 but worth the money for me.
Just bought the Garmin Zumo 396LMT-S EU. All good so far. I said I'd never buy a SatNav or a mobile phone .......
Keep looking in the for sale section you sometimes get a very good condition useable Sat Nav going for a bargain price. I did, thanks @crispey
I have had Tom Tom and Magellan, I really believe Google maps can be just as good IF you have a quality phone! There are various aps you can download to further enhance Google maps, there are plenty of bike attachments for phones hand free and Bluetooth can be used for voice instruction
I've got a TomTom rider 410 on the T100 and the BMW Navigator VI (Garmin) on the GS. TomTom is usually more intuitive but the Rider 410 isn't like the car models. In the car you poke a finger at the screen and you can then add a destination. On the bike model you have to touch the little round menu button in the corner of the screen, brilliant idea for people wearing gloves! On the my car model the keyboard has large square keys, on the bike tiny round ones, way to go TomTom. That said the Rider is a great satnav, I particularly like how when you're in a stretch of average speed cameras it tells you what you average speed is, the Garmin doesn't do that. At first I found the Garmin difficult to use, for difficult read different. Now I've been using it a while it's become easy. I don't have a favourite, I like some of the Garmin features but I also like some of the TomTom features that the Garmin doesn't have. At the end of the day both work and both get you there.
