Etrex Vista

[NOLA]

Got a used Etrex and was trying to get up to connect with my laptop using the serial plug
Computer was unable to connect with the GPS
GPS is set to Garmin
When it tries to connect it displays Check Wiring

Computer connects fine using USB port to connect to other GPS's

I believe I was in a similar spot a few years ago.  In my case I had an eTrex Legend that shares the same serial port cable at the rest of the early eTrex series.  The problem I had was my new laptop did not have a serial port.  But had four of the faster USB ports. 

I purchased an USB 2.0 to Serial Adapter cable.  The setup cost me about $20.00.  I have done business with this outfit for years without a problem.  A check on e-bay will identify other sources at lower prices.

The adapter I purchased came with a small CD with drivers so the computer would recognize the adapter.

The software that comes with it is critical to success.
