(at least for North America)
The prior version of North American maps (USA, Canada, Mexico and Puerto Rico) were 5,738 MB, and were dated December 2018. I updated my cards this morning, and verified that this latest version still fits on the 8 GB card, as it is has grown in size by only 60 MB (original size was 4,977 MB, almost 1 GB smaller).
If you are using macOS, we would like to inform you that after the latest macOS (Catalina) update, Fiat Toolbox won’t be operational anymore – you’ll need to delete the old version and reinstall the current version of the application.
This will probably be the last FREE 3-year map subscription* update for those of you that purchased their 2017 Fiat 124 Spiders in the Summer of 2016, like I did.
The map service is tied to your VIN, so don’t waste your money buying a new Nav card on eBay/Amazon, thinking you can restart the clock for another 3 years.
It is my understanding, that starting with the February 2019 version of Europe maps (which is currently the most recent version, according to Stuart), if you want the Russia maps along with maps for United Kingdom, Germany, France, Italy, Greece, Poland , Portugal, Turkey and Spain, you’ll need a 16 GB SD card to install them on now, instead of the 8 GB card. Mazda has a procedure for providing an official blank card to accommodate that, but I’m not aware if Fiat has done the same.
As far as I know, the ADR maps (Australia, New Zealand, Latin America, South Africa, Thailand, Philippines, Taiwan, Vietnam and Oceania regions) also still fit on the 8 GB card.
Procedure for Updating (if you skip backup, should take about 30 minutes)
Step 1. Download & Install Fiat Toolbox via Fiat 124 Spider Connect site (Windows or OSX version).
Step 2. Open Fiat Toolbox and insert SD card into the computer.
Step 3. Create a backup of the information currently on your SD card following the Toolbox prompt.
Step 4. Log in to Fiat Toolbox using your email/password combination. If it is your first time, you’ll have to create a user profile.
Step 5. Once logged in, a button will appear labeled “Updates” if a map update is available or “Device” if there are no new updates. Click “Updates.”
Step 6. Create a new SD card backup. If you have an alternate Nav SD card, you can skip this step.
Step 7. Click INSTALL to begin map update. After “Download progress” has reached 100%, “Installation progress” will commence, eventually reaching 100% as well. You only need to download once, so if you have multiple SD cards, updating after the first card, is much quicker.
Step 8. Once the new backup is compete, eject your SD card and return it to your vehicle.
* Starting this summer (July 2019), owners of 2017 124 Spiders will start losing their free map updates, as that only lasts 3 years. Unlike with some vehicle brands, at least the SD card will continue to function, so you could probably wait for a while before resuming map updates, but eventually you should expect to pay, unless you consider alternatives, like installing the retrofit USB hub, which will then allow you to navigate via Android Auto or CarPlay programs.
