TomTom spokesman Remco Meerstra told Reuters that the deal had been finalised some time ago.
Huawei, which had been using Google Maps on its Android devices, was locked out from doing so in May last year when the US placed it on a so-called Entity List which prevents it from using technology that has 25% of American content.
The Chinese giant released one smartphone last year, the Mate 30, using the open-source version of Android, without the proprietary Google apps such as Maps and YouTube.
The TomTom deal opens the way for the Chinese firm to use its traffic information, maps and navigation software to build apps for its devices.
Huawei recently released a Linux distribution it has developed based on CentOS which itself is based on the Red Hat Linux Enterprise version.
