Not where the ashtray is (that is where I have the Prodigy brake controller). But the head is where the sunglasses holder is and the base is under the console. Can put up photos if you want.
I have the GME TX3350 with MC634B mic installed in the ash tray compartment. There's a pic here: viewtopic.php?f=41&t=31476. Was a bit of a battle getting the ash tray out, but worth it in the end.
