The TomTom XL N14644 is part of the older XL GPS series (e.g. XL 30, IQ Routes 340S). The number N14644 refers to a regulatory approval—not a model name—and the device is considered end-of-life by TomTom, meaning it no longer receives official updates, including maps
Why N14644 Devices No Longer Receive Updates
Because of limited internal memory (often 1–2 GB) and the lack of an SD card slot, the XL N14644 series cannot support modern, larger map files. According to TomTom community experts, these models were declared obsolete and officially discontinued for updates
What Happens If You Try to Update
Although you can still attempt updating with TomTom HOME, the software may detect available updates initially. However, the process usually fails—leading to incomplete installations or device malfunctions. Some users have even reported their device becoming unresponsive during the update attempt
Update Process for N14644 (If Available)
If your device was among the rare exceptions that still qualify, here’s the general method used:
-
Install TomTom HOME on your computer (Windows or Mac).
-
Connect your device via the original USB cable and turn it on.
-
Launch software, which will automatically detect the device.
-
Review available updates—including maps, firmware, and content—and select them.
-
Install updates and allow completion without disconnecting.
-
After installation, restart the device and verify map/software version in Settings → About
Limitations and Risks
-
Most N14644 models are confirmed to be no longer supported and cannot receive updates due to memory constraints
-
Attempting updates could lead to installation failures—or worse—inoperability.
-
Community moderators advise it's often not worth attempting updates on these legacy units
Alternative Options
-
If your maps are outdated and no official updates are possible, consider upgrading to a newer TomTom model that supports Lifetime Maps or MyDrive Connect updates.
-
For built-in vehicle TomTom units or older hardware, you may find map files sold via third-party sellers or second-run TomTom referrals—but proceed cautiously to avoid compatibility and licensing issues.
-
Alternatively, explore navigation apps like Google Maps or TomTom AmiGO, which offer real-time and up-to-date mapping via smartphones.
In Summary
-
The TomTom XL N14644 series is end-of-life; official map updates are no longer available.
-
While TomTom HOME may detect the device, download attempts will likely fail due to memory limitations.
-
If your device still functions, consider upgrading to a supported TomTom model or switching to modern navigation alternatives for more reliable routing.
