I wish Alpine would make a processor unit attached to a monitor only via a cable like GME's TX3420 UHF radios for those without DIN entertainment systems. I have been installing Alpine's entertainment systems and CarPlays from my first car to my previous 2014 Mazda CX-5. If Mazda could design their cars' computer to have a port for CarPlays to be integrated into their dash board displays considering current model Mazda MZD Connects are barely competitive with Alpine units back in the year 1998. Even Mazda's proprietary retrofitted CarPlay / Android Auto to my 2017 MX-5 is slow to connect to iPhones / Nokias; has movement screen lock out / rotary centre console controller only enabled; cumbersome switching between CarPlay and terrestrial FM radio. I only use Apple Maps, not Mazda's GPS, do not care for FM radio particularly and I really appreciate Siri after trying Mazda's voice recognition.
