2024 Minnie Winnie infotainment on Accessory?

[MTBer]

I recently purchased a 2024 Minnie Winnie 22R with the Ford F350 chassis. On my first (and only) trip out I found that the Sony XAV-AX8100 infotainment system will not work with the ignition in the "accessory" position, it has to be in the "run" position which I don't think is good for the vehicle electronics. Does anyone have this same model and can you listen to the radio without the engine running? After the sale the dealer is totally useless.


Thanks

Hi Ed,
That is definitely not wired correctly. My radio / camera display runs either in the <Run> or the <Accessory> position. The video below showing the dash disassembly is for an older E-350, but the newer ones are probably about the same. Getting the radio out to connect power to the <On/Accessory> supply is a major project.

Thanks Eagle5, I think I will remove the doghouse and see if there are any obviously loose wires and then contact Winnebago to see if this is a Winnebago of Ford issue.

Dang, my 2021 22M has the same issue!! MTBer, please let us know what. You found and if you were able to correct it. Is this unit a Winnebago installed unit or from Ford?

This is the response from Winnebago customer support:

The radio should work on accessory. It could be a connection issue or an inline fuse on the wiring on the backside of the radio that is the issue. We would recommend you get an appointment with a Winnebago Authorized Motorhome Dealer to have them diagnose the Winnebago wiring to the Sony Radio that Winnebago installs. Feel free to locate a motorhome dealer from our dealer locator link below.

Thank you,

Well, I followed the advice from customer service and took the RV to an authorized dealer and was told that Winnebago tech support told him (the service tech) that Winnebago doesn't wire it up to the accessory position of the ignition switch. I guess I drove the RV 140 miles for nothing and I still have to go pick it up.

Hi MTBer,
How incredibly frustrating!!! Thank you for letting us know. The separate fuse for the accessory feed didn't make sense.
Ford provides feeds which are:

• on in both <Accessory> & <Run>
• on only in <Run>

The power wire will need to be connected to the <Accessory> & <Run> feed.
Because my 2019 radio is wired to <Accessory> & <Run>, this makes me think Winnebago will not admit it is a factory error.
If you still wish to get this fixed, I would ask the dealer where your 22R now resides "how much to fix it?." If it is too much, you might check with a local Car Audio shop.
I just called this shop:

Auto Addictions
3350 Saw Mill Run Blvd
Brentwood, PA
412-927-0495

The guy there told me the cost to fix your wiring would be about $100 ±$20.

After picking this up I will have a total of about $160 in gas for the two vehicles and 24 hours of time between me and my wife. (3 hours each way and two trips for two people.) The distance driven for this is 280 miles on the motorhome and 560 on the car for a total of 840 miles.

Its nice to get an apology but it really is one of those situations where an apology is no better than saying nothing. This is the response from Winnebago:

Ed,
I apologize for misinforming you that the radio should work in the accessory position. The Winnebago Techs that informed your dealer were correct. The reason Winnebago doesn’t wire it into the accessory is over a length of time it could wear down the engine battery. Sorry for your inconvenience.

Thank you,
Tommy

I should add that page 3 of the manual says:
Warning if your car's ignition has no ACC position
Do not install this unit in a car that has no ACC position.

I did consider a car audio shop since I knew it wouldn't be cheap to take this to an authorized dealer but I was concerned about warranty issues.

[Eagle5]

So Tommy at Winnebago tells us that the radio can wear down the engine battery, but we have that wonderful <Boost> switch on the dash if that were to happen.
Will you ask the dealer to fix it, and how much, or will you get your local Audio shop to do it, or just leave it as-is?

The only warrantee issues with work outside of either a Ford Dealer or a Winnebago Dealer is if the work affected the failed component. I would not be concerned about it.

I had the same thought about the <boost> switch and if they are concerned about the engine battery, there are wires to the house batteries right there that they can tie into.

I think I'll call the dealer back to get a quote and see if Winnebago will pay for it. I don't think they will but it doesn't hurt to ask. If they won't, I'll go the audio shop route.

After a few emails, some phone conversations, and finally a complaint to the Better Business Bureau, today I got an email from Winnebago telling me that they will reimburse me for the gas I wasted because of their bad advise. About 140 miles each way for the RV and two trips for the car. Thats 840 total miles between the two vehicles. Didn't get the check yet but I think I will.
