embeddable navigation engine for windows mobile

I've been working on an order management system for some time, about 1.5 years. It's written in .NET so I use .NET Compact Framework 3.5. All this time I tried different brands and versions of navigation software. In Windows Mobile (both Windows CE and Mobile) I had some problems managing 2 softwares, 开发者_高级运维our application and the navigation software. For a desktop solution it's easy to implement some mapping software to your solution, like MapInfo's ActiveX or a custom control working with Google Maps, Bing Maps, etc...

For any mobile version, I never found a navigation software which can provide a User Control which can be added to your own application, so you won't have to deal with 2 seperate processes.

So has anyone tried or remember a Windows Mobile solution like an ActiveX control or something?

I've used Bing Maas under the Compact Framework without any problem and without any "second app". It's not an Active X control, but they have a Web Service that is pretty simple to consume that provides map images as well as turn-by-turn directions.
