We have acquired an older Spektrum Powersafe Evolution AR 9200 and we are excited to begin using it!! We noticed in the manual that it needs 3-satellites to run, do these have to be DSM2 or can these be DSMX satellites? Does Powerbox do any check / refresh on older equipment before we do any install? It might be a good idea to have you check it all out. Lastly wondering if we could also hook up an OLED display to this unit?
