I'm a newbie
Hi all,
I have a Garmin Campervan 770 LMT-D which I connect to the internet at home (wireless) to update. Everything down loads fine but I it takes over 7 hours to download / install the new maps and update any new system features.
You would probably expect it to take this long when new and plugged in for the first time after being sat on a warehouse shelf for 12 months but was surprised that it takes 7 hours every time since when my old car Tomtom takes about 20 mins to update all the new maps!
Is there a faster method and does yours take so long to update?

We've got the previous version (760 LMT-D) and it takes around hour for ours to update. Having said that we've got 100Mb fibre broadband.
Your Garmin will be full Europe. Is your Tom Tom?

We have that model with full Euro maps. Takes normally around 40 minutes to download. Virgin Media 100meg.

I think it might be your internet that is slow. We have the same model and can take 1-2 hrs to update. I know our internet isn't the fastest.

I have the 760 and it says 4 to 5 hours initially but very quickly goes down and usually takes around an hour.

As others have said, it's your internet speed that is causing you an issue. Seven hours to update a map is well.........crap!
I too have this model and Virgin Media 100Mb broadband download speed. I can update the whole map in around 30 minutes. However, Garmin in their stupidity do not provide you with just the parts of the map that need updating but a whole new map and this is why it's such a big download. Up to 10 GB. I spoke to their technical people and asked them why they did not just update the changes to the existing map and they said this is something they were working on as they accept 10 GB is asking too much for an update, especially when people are on the road and many with restricted internet capacity. That was over a year ago and nothing has changed yet. On the upside it's only 3-4 updates a year. Safe Travels. In the meantime use somebody else's Wifi for your updates.

Think yourself lucky, my car one is 30gb and has to be downloaded to a usb stick then plugged into the car to update, again the entire map is being updated.

Thanks for all of the info all. I'm suspecting that it could be my internet download speed. We've recently changed from Sky to Talktalk but the downloads speed is pretty similar. I've just done a speed check and I'm down loading at almost 3mbps. Is that any good? We live in an area where high speed fibre BB is not available so I have a really basic package which is great for browsing / on line banking / emails etc etc but probably not for downloading loads of data such as an entire map of Europe.

Your Garmin will be full Europe. Is your Tom Tom?
Yes the Tom tom is full Europe and like many have said it starts off at 5 hrs and within 10 mins its down to 45 mins left to complete so I understand what you mean.

I will swap you a European road map 2020 for your garmin satnav ....
Got one of those too. Give me an old school paper map anyday, its just that they're so convenient when your passenger is not so hot on map reading. Know what I mean?

Just a thought? I wonder if I connect the sat nav direct to the PC to download / update instead of updating it using wi-fi? Would that speed things up?

Yes! 3Mbps is very slow and this is the cause of your long download time. Yes! If you connect directly to your Lap-Top with a cable it will be faster than WiFi. Faster still if you can connect directly to your router.

Download and install Garmin Express onto your laptop.
Once installed connect your sat nav to your laptop using a USB cable (one should have come with your sat nav).
Run Garmin Express and "register" your sat nav as a new device.
Run Garmin Express and it will find any software \ firmware and map updates for the sat nav.
If you can , connect your laptop to your router by ethernet cable rather than wifi as this should give you a more stable connection. 3Mb\s is a very slow internet connection. We have a 100Mb\s and could go to 200Mb\s if we wanted to pay more.

Yes. Next time I need to update / download maps etc I'l go done this route. There's a very good / short video on YouTube that explains the procedure which looks very straightforward.
