Warranty after fix for GTA02 GPS rework for SD card interference issue

[-stacy]

I did some testing today to add some more data points (or fuel on the 
fire, depending on your point of view :-)

What I did was run three test, one with the SD card removed, one with 
the SD card installed but idle and one with the SD card being used 
heavily. For each test, I ran simultaneous tests on two other GPS 
receivers to give a reference point.

The short version is that SD card activity really messes up the GPS, the 
long version can be found here (complete with pretty plots and tables 
and everything :-) :
