I am installing mine in the left hand hand pocket where the previous owner had a stereo.
The hole is already there and I am assuming that because he had a stereo there that a phone will be ok with the heat but we all know about assumptions. Did they ever make a stereo option for the St like they do for the beemers? I seem to remember the previous owner saying it was a factory stereo.
Where will you connect to the wiring harness?
