Just doing a bit of mod to Pete’s bike. The 2015 GTSes have a USB port in the glove compartment. With a bit of drilling, this can power a RAM mounted phone for GPS navigation. Basically, a more elegant version of my homebrew 12v outlet installation (mine also has the turn signal beeper from the linked installation guide). A few process photos behind the cut.

| Drill here, behind the left knee pad, into the glove compartment. |

| Put another hole in the knee pad itself and add rubber gasket around cable. |

| Pull to desired length. |
