some of my other thoughts with gpsd that I have mentioned in another thread are the possibility of extracting DGPS info from the RDS data stream and trying to pump it into gpsd... but that is for much later... and I have doubts the TripMate itself can be used with the dgps feature of gpsd...

Further to my original Step by Step plans are adding the functionality of being able to "mark" a waypoint via the empeg itself while in "nav mode" so that you can mark out a trip once while travelling it and then use it later... add to this the functionality of recording the audio instructions at the same time and you end up with the ability to record directions for a trip in the car while travelling it for later reuse... then you take that and build some software for use at home to do the same thing when planning a trip ahead of time with a geo-referenced map... ie click on a point to get the lat-lon and record an instruction... These instruction sets could be uploaded as units to the empeg and made selectable by a menu (the bitmenu (?) Frank has) and even exchanged with other empeg users...

More sophisticated waypoint matching would also match the direction you are heading...

Then you can add things like the flagging of speed traps... locations of Fast food joints... cheap fuel locations...
