I'd think your problem is more likely misconfigured drivers or software and/or slower PC hardware.

Have been told that USB cables shouldn't be more than 5 meters long. Even bought a 5 meter long special USB cable with built in repeater (haven't had the time to test it yet). Also on this package it's told that 5 meters is the maximum length for passive cables.

Though, earlier this summer I did a test and connected the Haicom (which have approx 1,5 meter USB cable) to 2 cables that were 5 meters each (a total of over 11 meters) and the GPS receiver still functioned just fine.

I agree that it could be a driver issue, but as far as I know I use the most up to date driver on the GPS receiver. Could it be other drivers (for example the Lilliput touchscreen driver) that makes the problems?

Still thinking about my friends identical GPS receiver that troubled when he was driving in curves, and my other friends identical GPS receiver that just died. Could it be a hardware issue on the receiver itself?

My cables are also stripped together, maybe there are interference problems?

Only thing I know at this moment is that it's quite irritating.

Will start to eliminate and isolate the problem in the next few days I guess.
