Phreeq Posted March 31, 2021 Report Share Posted March 31, 2021 I hope I'm in the right forum, if not my apologies. I'm looking for someone who can point me toward a thread that has the hidden menu access and/or bypass for AVH 521ex? Any and all information really. I love the unit but I want it to do more!
