Electric load

[3rdwheel]

.I'm the guy that was asking where I could hook up my GPS about 6 mounts ago, I got a response and found the wire. Now I would like to install a plugin for a double USB port for my IPOD and also my SCALA Q3 unit. The question is how much load can the wire used for the GPS handle using all 3 at the same time which will rarely if ever happen I asked the dealer and they very politely said that they didn't know.
GPS. IPOD, SCALA Q3 ON THE SAME WIRE.

If this can be done, where is a good place to ground the plug in for the USB port?

don't know about the SCALA Q3 but the GPS and Ipod will use less than 2 amps. The Gps I just purchased was fused with a 2 amp fuse, my I-touch works and charges quite nicely off of a 1 amp USB drive. I have my USB port wired hot and grounded through my add on fuse block. :yes::thumbup:
