Please download and print these firmware update instructions before downloading and installing the firmware update. It is important that you complete all steps correctly and in the order described below.

Choose from a host of entertainment options, including USB with Full HD video playback supported**, FM/AM tuner, or Bluetooth music streaming, Android Smartphone mirroring* (2-way via cable connection) all controlled from a large, highly detailed 6.8-inch capacitive touch screen.

Audio performance is supported with a 13 Band GEQ and highly detailed crossover adjustments just to name a few. Supporting either 4 x 50w Max direct speaker outputs or for those running external amplifiers, 3 Pre-outs (FRT, RR & SW). No matter what, we have you covered!

The best iPhone experience on four wheels; Apple CarPlay is a smart and safe way to control your iPhone in the car. Apple CarPlay enables you to make calls, navigate with Apple Maps, WAZE or Google Maps, listen to music, plus send and receive SMS messages.

Enjoy seamless connectivity and control of your Android smartphone in the car. Activate by using your voice, or the pressing the Pioneer touch-screen, Android Auto allows you to make phone calls, navigate with Google Maps, listen to music and send/receive SMS messages.*

Availability of non-Pioneer content and services, including apps and connectivity, may change without notice due to changes in operating systems, firmware, or app versions; changes to, restrictions on or discontinuation of the service or service plans; non-Pioneer hardware changes; or other events.

Stay safe and obey local hands-free laws with built-in Bluetooth (HFP). Easily pair a Bluetooth enabled phone without having to go through complicated settings. When a registered Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the device.

From hands-free calling, wireless audio streaming (A2DP) with artist, album, and song search, simple pairing, and control audio (AVRCP), Bluetooth wireless technology has made life in the vehicle much more convenient.

Reversing can be a stressful experience. The reverse camera input allows you to connect an optional camera for improved safety (visibility of hazards) and peace of mind, particularly when parking your vehicle or towing.

Have a DMH-1770NEX I bought a year and a half ago. About 3 weeks ago, screen went completely black and I thought the unit was dead. Then randomly the splash screen came on with vertical lines through it. Now the splash screen comes up that says NEX on it, but it never gets farther than that! Backup camera works. I have heard the AVIC line has a series of crappy sd cards, does this model have this as well?

I do not have the tool you have that switches the illumination and power supply on or off. But will that be okay if I connect the wires to a power supply generator and use a breadboard to give certain ground and voltages to the specific wires? I am thinking of creating a simple switch-button circuit for the illumination

@asd255 i know its been a while since you posted this, but i joined the site just to thank you...my 1770nex was freezing and rebooting nonstop...only once a white screen....when i pulled the unit apart, the chip didnt even look soldered, i flowed it, but also tapped it with the iron so i could actually see some solder...so far hasnt frozen once....so thanks very much!!!

Thanks for sharing, this helped me out too for DMH-1770NEX. So far my car radio seems better off, but the problem has been intermittent before the fix, so may take a week or two to know for sure if this fixed it on my end. There was nearly no solder on the pins as-is, so hoping this will stay ok.

I'm curious if anyone has the forced update files for DMH-1770NEX? I have the latest firmware (CUST_PIO.BIN w/ CUST_PIO.md5), but wasn't sure if the additional files (ISPBOOOT.BIN, ISPBOOOT.md5, turndegradedmode) from the upload are compatible with this model. Would like to do this just to have a clean firmware on the radio, just in case some files were corrupted on U27 (looks like it is ESMT's F50L2G41XA?). Thanks!
