Let's suppose you have a long trip planned.
Maybe 13-14,000 miles and 8-9 weeks on the road.
Let's say you want to get a GPS log of the entire adventure.
And, you want to be able to access the data with a map program, such as MS Streets & Trips on your desktop.
------------------------------------------------
I have MS Streets & Trips with GPS and it works OK.

But, after running for long periods on my notebook it does seem to have problems. I don't know if it is because my notebook is overheating, or what, but the map starts blinking on and off, and I have to save and restart the program. Also, I recently replaced a fuse to the 12 Volt port and my notebook is a prime suspect.
I've been checking out
DashDAQ with GPS, which may do the job. They claim it can log months worth of data on a 4 GB SD card. And, it will log more parameters than just GPS. But, it costs as much as a head unit with GPS built in, and I can find nowhere on their site that the data can be used with a map program on my desktop. The other features of the DashDAQ are great, including the Navigation. But, it is pricey. And, I'm not sure it will do what I want it to do.
I like Streets & Trips and paid something like a hundred dollars for it. But, if a logger which fit the bill in every other way has a cool mapping application that would be ok too.
None of the indash navigation head units I've examined have logging capaability.
---------------------------
In a nutshell: GPS data logger with large capacity and mapping software. Navigation is a
huge plus.
Any suggestions? TIA.
EDIT: Checked out TracWise (pricey), TrackStick Pro (capabilities).
If I could just figure out what the problem is with MS S&T on my notebook ... then, I'd have found the solution. Just not reliable enough as is.
