Sensational Nightingale’s writes – “$5 homemade bracket for mounting xm radio. My wife’s dashboard doesn’t have a single flat surface for mounting with double-sided tape. The radio manual recommends buying an aftermarket bracket: I found one for $40, but could not bear to pay so much for a little piece of metal. I bought a small sheet of 22 gauge steel from Lowe’s, cut it with snips, bent it in my vise, and drilled a few holes. “ – Link.
