Tomtom just released the new fall maps, version 855. We created a new thread here for discussion on these new maps.

Before you update your maps: We recommend the following steps to prepare yourself, prior to a map upgrade:

1) Make an explorer/finder backup. With any change this big on a Tomtom, it's always a good thing to back up first. Backup instructions are here.
2) After your backup, upgrade to the latest app. Earlier apps had issues with map installs, so you should update your app to the latest version before attempting a map upgrade. To update your app, choose "Update my Device" in Tomtom HOME, and if an application is offered, check the application and uncheck everything else, and click update. Keep repeating these steps until HOME has no newer application to offer.

How to download your map:
- Maps must be downloaded via Tomtom HOME. You can install Tomtom HOME from this link. There has been a recent critical update to Tomtom HOME (version 2.7.6.2056). If you have issues installing the HOME update, check this thread.
- If you're device has been used for less than 30 days and you haven't downloaded a map before: You should get a free map under the "Latest map guarantee". To use this guarantee, open Tomtom HOME, and go to Tools -> Latest Map Guarantee
- If you have an active or lifetime map subscription: Open HOME, log in with your email/password if not auto-logged in, and go to "Update my device". The new map should be offered automatically for download.
- Otherwise: If you want a new map you have to purchase one. Open Tomtom HOME, go to "Add maps", and follow the purchase steps. You can buy a single map, or you can buy the "map update service", which bundles current and future maps for a discounted price. Note that purchases are processed through Netherlands servers, so you often pay more than the quoted price due to foreign credit card fees. Also, you may need to call the card company first and tell them you plan to make a purchase from a Netherlands website, so that the charge won't deny.

Issues to consider when updating maps:
- Reserve enough time for the map update. Maps are 1 to 2 gigs in size, and can take a long time to install. You'll need time to download 1-2 gigs from Tomtom's servers, and then you'll need an additional 20-60 minutes to copy the map from your computer to your Tomtom.
- If you try to download when everyone else is trying on August 31st, the download could take up to 4 hours due to server congestion. Also, it may abort due to the overload. If it aborts, go to "update my device" and the download should resume from where it left off
- If you're device has app 8.x, you'll lose favorites and settings after the map update. To restore the from your backup (as recommended above), follow these steps, and then follow these steps.
- Inevitably, something breaks for certain models in the map update process. If you have an issue, check out this thread, to see if others are reporting a similar issue, and if anyone has found a workaround/fix.
