Comment 15 for bug 508013

Be aware that upgrading gpsd to 2.92 or higher will break clients that are not in synch. 2.92 stripped out the old protocol.

Roadnav is one such client. It isn't available from the Ubuntu repos, but it is available from getdeb. I have it working with 2.92 (on Karmic), but not in a form I'm willing to release.

I think the version of gpsdrive in the Lucid repo is another.
