whitespace-normal\" data-sourcepos=\"104:1-104:412;6493-6904\"\u003eThe factory amplifier in the CX7 ER Series 2 is designed to receive a specific signal level at its input. The AM905D head unit outputs at a higher level than the factory amplifier expects. Without the line level converter (which steps the signal down to a safe level), the excess signal can overdrive and damage the factory amplifier. Using the AMDMZ20 (non-amplified kit) on an amplified CX7 has the same risk.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\" data-sourcepos=\"106:1-106:52;6906-6957\"\u003eHow does the AMDMZ21 differ from the AMDMZ20?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"107:1-107:321;6958-7278\"\u003eThe AMDMZ21 is for factory-amplified CX7 variants; the AMDMZ20 is for non-amplified variants. The AMDMZ21 retains the factory amplifier using the line level converter integrated into the SWC harness. Both kits retain SWC (excluding phone button) and vehicle menu. Neither retains the factory reverse camera, USB, or AUX.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\" data-sourcepos=\"109:1-109:75;7280-7354\"\u003eDoes the phone button on the steering wheel work after installation?\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"110:1-110:207;7355-7561\"\u003eNo — the phone button is specifically not supported by the AMDMZ21.
