Terms of the deal were not disclosed.
The Ford-Google deal comes at a time when some governments and regulators are starting to ask questions about the power of Big Tech.
Last week, the Australian Competition and Consumer Commission - which has a lawsuit in train against Google for alleged privacy breaches - issued a report warning against what it called the search giant's "remarkably dominant" position.
A spat over a bill that could see search engines being forced to pay for news saw Google threaten to pull out of Australia during a January 22 Senate hearing.
The front-foot ACCC could also potentially derail Google's purchase of Fitbit.
What the Google-GM deal means for iPhone owners?
In short - nothing
iPhone owners will still be able to connect their handset to a Ford for calling or music, and the company's cars will still support Apple CarPlay and Android Auto.
More partnerships on the way?
Hyundai shares went on a US$8 billion surge after the Korean company said on January 8 that it was in talks with Apple on developing a self-driving electric car.
The Korean company put out a revised statement just 30 minutes later, saying it was one of several automakers in talks with Apple.
A few hours later, a third version of the release had watered things down to a general statement that Hyundai was in "early stage" talks with several un-named potential partners about an autonomous EV.
In December, a Reuters report, based on an apparently leaked document and statements from unnamed insiders, said Apple planned to produce a self-driving electric car by 2024, complete with "next-level" battery technology that would offer a long-range at low cost.
