I couldn't seem to find a good answer on this, so I apologize if this has been asked before. I was wondering if an Aspen E5 with ACU can be installed by an "traditional" A&P/IA instead of a dedicated avionics shop/authorized dealer? I believe the Garmin G5's can be, but could be wrong on that as well. Even if they can, would you recommend it? Anyone with any experience? I am trying to figure out a good way of replacing my DG as it is not working well, and don't really want to wait 9 to 12 months to get into most avionics shops.
