2010 Explorer Kenwood DDX374BT - Stuck in Rear View and 3 Red Flashes

Post by roamin » Mon Oct 29, 2018 12:00 am

I recently purchased a used 2010 Explorer that has a Kenwood DDX374BT w/ Maestro RR and aftermarket back-up camera installed. Everything was working great until the other day when the radio all of the sudden switched into Rear View mode with sound only coming out of the factory subwoofer, then the sound cut out completely and the radio stayed in rear view mode. I could use the touchscreen to get out of the rear view screen and select different sources, but no sound comes out no matter the selected source. When I turn the radio off and on (or press reset), it goes straight into rear view mode. The next day, my wife tried to insert a CD, which the unit accepted but it wouldn't play, so she hit eject and the unit ejected the CD but now just continuously ejects like there is still a CD in it.

I found a post on this forum about Kenwoods commonly needing firmware updates for the rear view issue, but I can't get the unit to start the update. I can get to the firmware update screen where it asks for the USB media, but when I insert the USB stick nothing happens (tried it in the factory (SYNC) USB slot and in the radio's wired USB slot).

Today, I pulled the radio out to check the purple/white wire to see if it was shorted out, but found that it wasn't connected to the Maestro unit and instead was just wired into the rear reverse light like "normal", and wasn't shorted at all. I disconnected it completely, but the radio still goes into rear view mode as soon as you turn it on, and still won't play any sources (and still constantly tries to eject a CD that isn't there).

As I was putting everything back in the dash, I noticed that the Maestro unit was blinking red 3 times. I've found several posts about 2 blinks, but nothing about 3. I'm kind of assuming I need a new radio, but is the Maestro unit okay? What do the 3 red flashes mean?

Thanks in advance for your help!

There is no such thing as 3 red flashes. We have one slow red, and 2 red.

Okay, thanks Dara. I was wondering if I was remembering correctly since I couldn’t find anything about 3 flashes. Will check again this evening to verify what it’s doing.

Pulled the radio out to check again and it's 2 red flashes. I performed the reset on the Maestro and got a solid green flash, but then it went right back to 2 red flashes. Connections into radio and Maestro unit all appear to be good, so I'm assuming the radio has just gone kaput on me.

Will be replacing the Kenwood with a Pioneer AVH-501EX later this week....will I need to re-flash the Maestro or do anything special? Or can I just plug-and-play, so to speak?

Thanks again for your time and guidance. Much appreciated.

You must re-flash the maestro and tell us the new model/serial number of the radio for everything to work properly.

Stupid question maybe...do I need any other equipment to flash the device or can I plug straight into a laptop and do it? I noticed in the idatalink site that there’s a Weblink cable that says it’s for connecting to a PC. Do I need to buy anything else to flash it?

You just need the USB cable that came in the box with the RR. The weblink cable is only used for our remote start products.

Gotcha, thanks. I'm assuming a regular USB cable will work, correct? The unit was installed before I got the vehicle, so I don't have anything that came with the Maestro other than the connectors that were used to install it.

Thanks again!

Many thanks! Installed the new Pioneer unit today and everything works flawlessly. Re-flashing and hooking up the Maestro was a breeze.
