Sorry pj I seem to have kicked off a train of unhelpful responses. I seriously thought the 2nd gens all came with SXM these days (even the 5 inch radios), but maybe not. Anyways, I've looked around the dash before to try to find a good place for a dedicated standalone GPS or phone mount and its slim pickings, like the dash is full there is hardly anywhere you can put anything that doesn't block either some buttons, part of the screen, or vent airflow.
Android auto updated recently and it just occurred to me, why doesn't SXM have an android-auto compatible app like Spotify? If you have android auto that would do the trick if SXM would update their app to be AA-compat.
