The FCC application for the Uniden R7 was recently updated requesting a Class 2 permissive change. I think this is basically a recertification due to having to change the MCU, voice IC, and various passive components, likely due to recent chip shortages. It will be interesting to teardown new units and see what has changed. The application notes that no changes have been made to the RF side, so I doubt this will have any impact on performance (although I'm sure it will be tested).

Can you share what chips/passives had to be changed?

In general, could a MCU change impact performance if the RF section remains the same?

Hey guys do yall see any light at the end of the tunnel, with the chips shortage or will new tech companies step up and start making them for cars and radar detectors and whoever needs chips for electronics?

Same as Uniden, problems getting main MCU, GPS chipset, voice MCU, various passives. Nothing should change performance wise.
I would love a video or blog post, post DS1/Theia release, where you can talk about how you handled the supply chain issues, sourcing of parts, etc. I think the backend manufacturing process is incredibly interesting, especially as someone with zero background in it. I can only imagine what it must be like to search for vendors with compatible/suitable parts for a new product.

I wonder if this will mean there will be different firmware for the new version?

Quick update on the topic. New R7's are now being shipped with the new ST microprocessor. From what I've been told, performance and features will be unchanged. It's just a component change due to parts shortages.

New R7's are coming preloaded with firmware 1.40. (I think it's the same as original R7's with 1.37, but I'm double-checking on this now. Edit: Confirmed that 1.37 = 1.40.) I'm not sure yet how else you can tell the difference between versions, but the change is happening now.

(It kind of reminds me of Escort changing BT chips with the Max 360 and how there's two different firmware versions depending on which BT chip and serial number you have. That said, there were some changes with the BT pairing process with the Max 360. I don't think there will be any noticeable changes with this R7 change.)

What's the different between the firmware if we know?

I just bought an R7 and it came with the 140.147.119 firmware, but I accidentally flashed is back to 137.

Can't find a download for 140.147.119

Not sure if it will lead to any issues or not...

It’s the same, vortex just mentioned that the firmwares are identical.
So I can confirm that it does matter. GPS does not work if you are using the wrong firmware. Uniden support says to return the unit and buy a new one. They cannot send me the correct firmware.

Whaaaaaaaaaa?! Seriously? They can't send you the correct FW? That's nuts. In the very least they should have put something in there to make an update fail if you try to load incompatible firmware but not even having compatible FW on hand to allow users to fix the issue?

Just reload the prior firmware if you have an issue with firmware. Check the recovery mode and it will overwrite all firmware.

That is pretty dumb. Let me see if I can get ahold of 1.40 to send over. :)

How does this work if you don't have the 1.40 FW and can't get it?

If Ariel cant get it from Uniden I'll get it from Attowave... I am sure someone at Uniden has it but sometimes the general guys you get on the phone are not familiar with all the product lines in detail.

This is incorrect information posted by me, just letting newer members know to NOT flash 1.37 on to the new R7 with 1.40 firmware, you will have firmware that is separate for your R7 and flashing firmware not for your device may lead to errors due to incompatibilities between the hardware and firmware.


Thank you for listening to this message, you may now return to your daily activities.

Thanks all. I got the same response from 2 people at Uniden over the phone. While I would normally push for a better resolution, I decided to just reorder a replacement on Amazon. Not what I wanted to do, but I don't want to jump through hoops and Amazon makes returns quick and easy.

I did the same thing. I flashed 1.37 over 1.40. Since I'm using a MacBook, the version of the flashing software is 1.4 - so I thought that's what was being displayed. I realized my mistake once the version changed to 1.37 after the flash. I figured "No big deal, I'll just find the correct version somewhere on the Uniden website and flash it back. Instead - doing a google search brought me here.

I called Uniden. They will not send me 1.40. I was able to find a Best Buy near me that had it in stock so I exchanged it because "The GPS function isn't working". Ironically, the new R7 I received is flashed with 1.37 and the S/N is about 1500 lower than my previous one. So I guess the new one is on the original hardware.

This is a UX failure on Uniden's part in so many ways.

1. No warning on the website where you download the firmware. (This should be an easy fix for Uniden).
2. The devices with newer hardware allow for a flash of incorrect firmware (OK - This could be difficult to set up on the device)
3. The latest flashing software allowed me to flash to an incorrect device (At least a warning pop-up should be added to the latest flashing software).
4. The my.uniden.com website (where you register your device and takes your S/N) has a different firmware download experience. After I registered my device - and the website KNEW my S/N - and I click on "downloads for my device" - it presents all the incompatible versions of the firmware. (Of course 1.40 is nowhere to be seen.) (This is a major fail by Uniden. They know my S/N and should not present me with the downloads for that device.)
5. Even contacting customer support has no resolution other than to return the device. Why is the firmware good enough to install on shipping devices by not good enough to make it available to the public in some fashion? I can understand not posting it on the download site because people with older hardware will install it, but at least make it available for those that call with this specific problem.
