No idea where to ask this so I've come here. Point me in another direction if there's a better sub.


I have an old Holux USB GPS receiver. I think the model is GM-210. I have no use for it as a USB device, but do need it to go into a D-sub 9 port.

Can I just snip the USB end off of it, take the power leads and re-terminate them to a 5 VDC source, then take the other 2 TX/RX wires and terminate those to the D-sub?

Will that work?


Doubt that you'll find the answer here, these forums are for the support of the free maps at GPSFiledepot. Not sure where else to ask, 5 or 10 years ago there would have been lots of places, but today the same sites are mostly ghost towns. LaptopGPSWorld is the only site I can think of, but I wouldn't hold out too much hope...


There is a utility software - GPSU - that interfaces with many types of GPS unit. Maybe post the question in their user forum.
