Hello,
Recently the radio in my 2014 is250 with the ML system has been plagued by the boot loop issue and after taking it to the dealer I was told that I needed to replace the radio. I have been scouring the internet and haven't been able to find the exact model that is in my car but I have found radios that are from a 2015 is250 with the ML package. My part number is 86130-53041 and the ones I have come across online are 86130-24021 & 86130-53N02. Are the 2015 radios compatible in the 2014 IS's?

After taking out my radio, I noticed that the radio's are identical all around except my radio has a brown plug. This brown plug, however, had no harness plugged into it and isn't in use on my vehicle. Can anyone shed some light on what the brown plug is for?


I am trying to get my radio replaced without breaking the bank and the price the dealership gave me nearly made me choke. Any assistance/recommendations into this matter would be greatly appreciated.

 

Seen an ‘unused jack’ on other brand vehicles too. Could have been for an option that was not equipped on that car, or never offered, or a test harness on an early design, removed on later revisions.

 

Thank you very much for your prompt response. Do you know whether the 2015 radios are compatible in the 2014s?

 

I don’t know definitively, but given the fact that all the jacks match, except the unused one, and there is only one model year difference on basically the same car, I’d give it a whirl. Probably will work fine. (As a similar example, I have a 2011 Jag XF unit, that has been loaded with the firmware for a 2009 Jag XK, installed in my 2007 Jag XK, to get some ‘newer features’ not available in 2007, and I didn’t have access to an actual 2009 unit. Works fine. Has fewer jacks than my original 2007 unit.)

 

What's the faceplate ID number for your 2014 radio? It's at the bottom left on the face of the radio.

 

My face plate says P10436.

 

Based on that faceplate ID, you should have the ML radio 15 speaker system without navigation.
This radio was also used on the 2015 model, but I don't believe it was used in 2016 onward.
Regardless of the extra brown connector slot, once you find a radio with the same faceplate ID or part number, it will work in your vehicle.
As you noted there was nothing plugged into the brown slot anyways...also that faceplate ID will always be associated to that part number, and vice versa.
The brown slot could have been for early production radios and eliminated down the road.
The other two radio part numbers you quoted: the 24021 is for the RC, and I'm not sure about the second one.

 

Ohhh wow, that is very interesting because my system does have navigation in it.
I am having a hard time finding the exact radio and faceplate ID online, it being a Canadian model and all.

I see that the model number I provided "86130-24021" is from and RC, despite the radio looking identical.
I have found this one from ebay: https://www.ebay.ca/itm/2015-2016-Le...53.m1438.l2649

It states that it is compatible with the 2015 is250 and was wondering if this would work with my car? What are the determining factors from radio to radio that would dictate whether or not it will work across different models?

 

It makes sense it does have navi...gotta take these online parts catalogs with a grain of salt sometimes.
For the eBay ad, it states it will fit 250 C (convertible) as well, which is really a 2IS body style, which has a completely different radio altogether...so there's no way it would fit.

Based on the list below, it looks like a P10998 radio will physically fit/plug into an IS, but may not be functionally compatible...plus you would likely need a micro SD card with the correct map data...so that's another $200.
You will notice that the part numbers are different, this is likely due to the fact that the radio comes with the mounting brackets, therefore a different package part number than the actual radio itself.

 

Thank you for this information, I may just take a swing at it and order this radio based on the information you have provided me. I noticed that there is an SD card plugged into the back of the radio's, maybe I could swap mine into the system, considering of course that it is not directly paired to the respective radio. At this point, I am not too concerned about the built-in navigation as I may be opting for the 10.5 inch android screen from 4x4 Shop as I haven't been using the built-in maps due to them being outdated. My main concern is whether or not I can get the system up and running and have it drive the amp and speakers.

 

There is no SD card in the back of the radio, the only card is the micro SD card in the front.
If you're referring to that card like piece under the black connector at the top, that is the circuit board.
Without the micro SD card I'm pretty sure it won't boot up, it will just ask you to insert the card continuously.
And you can't use the card from your unit because it's married to the unit already.
It would be a gamble for sure.

 

When I took my radio out there was a little door held down by a screw on the right side of the unit and behind it was an SD card, I thought that maybe this was for the OS. I have circled it in red below.

 

I do believe you are the first to discover that. It's quite reasonable to assume it may contain the OS.
I've never seen it available separately or mentioned before.
If you happened to take it out, was there any writing or markings on it? Now I'm curious...of course I'm not ripping out my radio to check mine lol

 

It was a generic 8GB SD card. It didn't have any Lexus branding on it, and it didn't have any numbers etched on it that I remember.

 

I wonder if the micro SD card gets married to the SD card...and not really the physical radio.
It would be interesting to see if you swapped both if the unit functioned normally like your old unit before it started rebooting.
