We have heard the CoPilot is not planning any GPS Navigation products for Windows phone 7, and now it seems Tomtom is also joining the bandwagon.
Monsmartphone has asked Tomtom is they are planning to support the new OS, and received this response.
We have read your e-mail for a future product Tomtom compatible with Windows Mobile 7.
We have yet no information about it, so we are unable to tell you a release date or even if a future compatible product is expected.
We appreciate your understanding.
This makes Navigon the only real turn by turn navigation product for Windows phone 7, and this is generally only available via carriers. It is likely however that when the Windows phone 7 installed base reaches sufficient size we well see more interest from the other companies.
