Had a 2YO Pioneer W4400NEX die (forever 'loading'); tried to put in a new SD with firmware and that didn't work, so I'm looking for new Head unit. A local shop has a good deal on Nakamichi 6605.. no wireless CarPlay, but not sure that's essential. Anyone know anything about these units- features, sound quality, reliability? With pandemic-related manufacturing issues, it's not easy finding any Pioneer/Kenwood, and with my recent experience, not sure I put Pioneer in the reliable camp anyway. Appreciate any advice!!
