NeW to the forum....aside from owning 2 mx5’s, but our 2011 GT has the BOSE sat (non nav) audio unit (TG17669RX). Works fine but we now have a purple/yellow line running down the left of the small screen (looks terrible)I’m thinking of just replacing with a used unit (they all are about $90-135 used)....are there any issues I need to be aware of with swapping TG17669RX unit with another used TG17669RX unit? Assume we will need to call XM to update our plan with a new #, just want to make sure this is doable. Not sure if radio code will need to be reset on the used one or not.
thanks for any help you can provide!
