Default Navigation on Chromecast?

Hi there!

I have a Chromecast that works very well with YouTube and other supported apps, but I want to know how I can use navigation on Chromecast?

I have my Chromecast connected to the head unit of my car and I want to use Google Maps or Sygic with the Chromecast. Does anyone know how to do it without the mirroring feature? I don't even have a Nexus so it will either take a long time or Google will never release a Google Play update for my phone to support mirroring to the Chromecast.
