There is quite a raft of GPS software out there as well, I'm not sure what you've tried but I've had a go with a few that give you GPS information rather than Sat Nav
With my work I get to travel a lot, but I already have quite a good directional sense and use maps a lot more than the SatNav (Navigon Navigator 5). I tend to use SN merely for navigating at the other end (the complicated bit) or driving through new cities and the like. Oh. And London
Anyway, so, yeah. GPS Software.
GPS Tuner (Megalith Software)
This shows a whole raft of information that it can collect from the GPS. Satellite information, direction, Altitude. Deal with waypoints, tracks, routes and you can load you're own maps as well. (Commercial Software).
GPS Viewer (Free/Limited Access)
I think this is some basic diagnostic software for the Holux GPS receiver. I 'found' it online somewhere after I bought a Holux receiver of ebay that turned out to be a Holox! Oops.
Anyway, it gives you're basic GPS info. This has the added ability that you can "scan" for a GPS port, or select one manually. Under GPS Status it lists the actual satellite information, date, time, lat, long and DOP. Lower down it has you're direction, speed, altitude and PDop. Basic diagnostic info is good enough for it, but although it's installed it doesn't use much memory and isn't used much for other.
GPS Dash (Commercial)
This is an amazing bit of software and I totally love it! Had a few issues with crashing a while back, usually after it's been on for a 12 hour day of driving and stuff, but I think that was user error :/
When you start it looks like a bunch of car speedo's. You've got an amazing chose of what you want in those little dials. 5 small dials and one large one, it has a day and night scheme and comes preinstalled with "profiles".
You can also manage routes, waypoints, charts, maps as well as see the raw GPS data. Tap on a "dial" and you can see that one in full screen. Each of the dials can show the following:
Speed, Accelleration, Milage, Altitude, Ascent Rate, Altitude Gain, DPos (Current, Max, Min, Average)
Navigation (Heading, Distance, ETA), Time (Local, UTC), Reception (SigQual, SatID).
Maspware GPSMeterPE (Commercial).
This is a new bit of software I've not tried out yet but looks promising
Looks like it has full screen capabilities too...
Memory Map (Commercial)
You might have heard of this already. It gives you an OS map to follow on the screen. If you want to know where you are with OS type acuracy then this is the software for you
But it is pricey. I think mapping for the entire country is about £900 !!!!! I've got West Midlands and Wales
As for other "Commerical" software I've also got PocketIRC which seems a lot easier to use than WMIRC. Alas can only use one server at a time but for the time being this is ok for me
This is now where you tell me I've posted in the wrong place
