I had previously installed a XM radio on the cup holder area.
XM radio installed on cup holder.
I decided to see if I could fabricate a mount to place the SGIIon top of the radio. First I added a strip of Velcro on the length of the radio and SGII. This Velcro strip held the SGII, but was a little floppy.
Using some metal strapping, I was able to make a mount to attach to the radio. I had to bend the strapping using a hammer and vise to get a tight angle. I then wrapped the metal straps in duct tape for protection added Velcro to the side of the mount and SGII.
