Ask HN: Where did Nokia sold Here Maps for such a low price?

Nokia bought Navteq for 8.1 billion USD back in 2007. And sold it to BMW/Daimler/Audi(VW) for 2.78 billion USD in 2015.

The lost of valuation seems a bit odd at a time where maps are a critical asset for tech companies (self-driving cars for instance...).

Do you know why? Was the technology not that good?

Subsidiary question: Why a technology company (like Uber, MSFT or Facebook) didn't buy it?

Thanks
