RR firmware for 2019 JVC touchscreen receivers on Jeep Commander XK/Grand Cherokee WK

Post by Pau1ey » Sun Mar 10, 2019 8:20 pm

I only see RR2 firmware available for the new 2019 JVC KW-M855BW and KW-V950BW. Will RR firmware also be available soon or not at all? The vehicle is a 2008 Jeep Commander with factory RER MyGIG radio, RES, backup camera, SiriusXM, and Boston Acoustics so it'll get the CH1, SAT1, AV1, & Mastero. Also will the rear VES be retained? This Jeep has the overhead flip down screen and 3 RCA inputs on the back of the front center armrest console, no external DVD player like the 2006-07. Head unit has video out. Thanks!

Bump... Anyone from iDataLink tech support here? Also just cross-posted this in the main CDJ forum.

The RR2 has not been released as of yet however, the RR is compatible and both radios that you listed are on the site available to flash. Backup camera and RSE are retained when using the AVCH1

^ What Justin said. This is a clerical error on the site, but will be fixed ASAP.

So I have the JVC KW-V950BW, the Mastero RR (4.3 firmware), CH1, SAT1, and AV1 all installed now in my 2008 Jeep Commander which had factory MyGIG RER navigation and rear VES but a few things aren't working that I've noticed so far:

Rear VES - it will not work at all with your Mastero RR, CH1, SAT1, and AV1 combo setup. VES is grayed out/not selectable in the JVC menu, so does RR firmware prevent video out even if I had a non-OEM/VES monitor? I tried flashing the RR to 2008 Dodge Durango firmware as it shows it as VES compatible with AV1 but it didn't work either, it was still grayed out. After testing your competitor's Axxess AX-ADCH100 kit the rear VES works exactly like it should, displaying whatever movie I have playing on the JVC head unit. Their AV plug looks exactly like yours except it has 3 separate wires which I had to ground instead of 1.

EVIC Cluster - Your website shows "EVIC CLUSTER DISPLAY (IF EQUIPPED)" will have these features with my particular radio: Source Name Display and
Navigation Guidance Display. Neither of these show on my EVIC.

Park Assist - Your website shows "PARK ASSIST:" will have these features with my particular radio: Distance Display on Screen. I have OEM park assist but it is grayed out on the head unit and doesn't show anything while backing up. The Jeep shows distance via a roof-mounted LED strip near the tailgate that you see looking in the rear view mirror.

SiriusXM - I chose "Seek +" and "Seek -" for steering wheel controls and they literally go 1 by 1 through each channel in order. With my OEM setup they would at least skip to the next preset, which would be ideal as SiriusXM has a ton of channels to skip through while driving. Also I tried the "Band (FM,SAT) & Folder +" and "Band (AM) & Folder -" and those didn't cycle through presets either. Is this something that can be changed in the Maestro RR firmware?

Thank you in advance for your assistance.

The VES option in the radio touch screens is only available when we do toggling between OE sources on certain applications. The AVCH1 should simply be a pass thru for the video signal going to the rear monitor. It is possible that with it working with the Axxess piece you noted additional grounds that were made, one of them being some sort of video enable to the rear monitor. We would have to look into that and see if that is in fact the case.

What source are you using, trying to get info on your EVIC cluster display? Does it show info in any sources, like FM radio, CD, etc? The navigation prompts are only available from navigation equipped headunits, not when using apps that allow navigation. If that makes sense.

Park assist only shows distance until object, and the park assists icon becomes active on the radio, when that distance until object info is available on the MSCAN network in the vehicle. Many early models that have separate displays/audio alerts like yours do fall into this category.

The way the steering wheel buttons operate does not change from source to source for us. We send the same command to the radio regardless of which source the radio is in, whenever the button is pressed. If you change the button to operate the way you want it to in one source, it will change the way it operates in all sources.
