Question Upgrade RA3 to RA4 and void warranty?

I recently bought a like-new, pre-owned Latitude equipped with the RA3 (8.4A) Uconnect system installed. The previous owner must've balked at the $600 activation fee, because the nav was not turned on. As I was pondering whether to bite the bullet, I found an RA4 (8.4AN) unit on Ebay that had been pulled from a wrecked Limited. For considerably less than $600, I could have 3D nav and HD radio, just by switching out the head units. It seemed like a no-brainer to me, so I jumped on it.

Swapping out the head units was a piece of cake (YouTube is your friend!) and the job was done in 20 minutes. The Ebay seller provided the anti-theft code and I quickly unlocked the unit, thinking I was good to go. But nothing is ever easy. The screen displayed controls for heated seats and dual-zone HVAC, which I don't have. But the larger issue was the blinking odometer! I came here to my new home for help and learned on another thread that the flashing odo is the BCM's way of telling you that there is a "mismatch" onboard.

I took the Jeep to my local dealer and they flashed the BCM to recognize the new RA4 and reprogrammed the head unit to recognize the equipment on my Jeep. The service advisor told me this was non-warranty work, so I paid $50. The odometer displayed steady and the on-screen controls match up to my vehicle, plus I have a beautiful nav map.

But I'm still not out of the woods. I'm a bit of a tech geek, so I checked the system software version, which is 14.05.3. The current version is 15.26.1. So I went to the Uconnect site and downloaded the update, loaded it on a flash drive and plugged it into the USB port. The system recognized the update and went through the motions of upgrading, but at the end, it displayed a message like "Mismatch! Attempted to install VP3 but VP4 is needed."

I figured it was because Uconnect associates the old RA3 with my VIN. So I called Uconnect customer service and asked a young fella named Les if it was possible to associate the new RA4 with my VIN, so updating would be easier in the future. He said that not only could that not be done, but that switching out head units not done by a dealer could void my warranty. Yikes! I still had half my factory warranty left. I've already sent my RA3 to the Ebay seller for a core reimbursement.

So my questions are: Have I screwed the pooch? Have you heard of this? Anyone know of a "back door" to get software updates? Would you be worried?

Some dealers will use that excuse; anything non factory in my experience the dealer will blame the issue on the none oem/dealer part installed. Especially when it comes to HIDs headlights in my experience.

Although the dealer must prove that particular part was the cause of the issue.

On a different note I myself am looking to upgrade from my 5.0 to an 8.4

Good luck with everything

Hey @graphicswizard I'll give you my VIN so you can download it. As for warranty it's a bunch of crap! They'd have to prove that the work you did caused an issue and only in that case would you have a risk. Sounds like a phone jockey reading from a script

I am certainly no expert on the electronics on this Cherokee.
I think it is amazing you did what you did and it works with the help of the dealer's reprograming.
I doubt very much if you are endangering your warranty, except if the head unit goes out. The key he said is "could". I am sure that the unit itself is not covered as it is not associated with the VIN.

As far as the mismatch goes all I can say is that dealer needs to become your best friend. I am sure he can do the updates for you if they are really needed.
For a fee the dealer may even be able to associate the new unit with the VIN to your Cherokee. I really do not see an issue with an OEM part being installed to upgrade your Cherokee. The VIN just needs to be updated to include that new part for update purposes. Then you can download. They may not cover it under warranty but again it is a OEM part. That is the dealers call.
The dealer actually was able to update the software to your vehicle from the Limited. So I am sure he can handle that other little problem. Also the fact that it your new unit works OEM, verifies a satisfactory install.

As you have found out all the parts are interconnected by software and thus all the parts must match the original configuration.
Also you found out the dealer can take care of that.
It sound like you have a good dealer that works with their customers.
I would be sure you have them do your oil changes etc. to cement your relationship.

Thank you, Ruffnredi! The same "phone jockey" thought crossed my mind. I had wished I had a VIN that would point me to the correct download link. I would get the right update file and nobody gets hurt. I don't expect you to publish your VIN. Is there a way to PM here?

Thanks, Jeepster1 ... I've found that it's a good idea to establish relationships in all the domains of life, which is why I searched for and joined this online club. Not to mention that it feels good to be part of a community built on a particular interest. I've told the dealer personnel that I've "adopted" them, and I do plan to have them do my oil changes.

The download file name is UCONNECT® 8.4A_RA3_15.26.1_MY13_&_M14
and it unpacks to a disk image named swdl.iso
My build date is 03/06/14.
