Absolutely nothing wrong with it.

I personally got one to work in a couple of hours, including the drive 
to the parts store to pick up an RS232 connector and a short USB cable.

The USB cable has 4 wires, with +5V on Red (Black is Ground), so I 
simply soldered the relevant Garmin wires to TX/RX/DCD/PWR/GND, 
connecting the USB Red/Black wires to the last two.

That's all I needed, and the GPS "just works" like this. :-)
