Uniden R8 Firmware 1.25

Uniden posted firmware 1.25 for the Uniden R8 this morning on their website. This is the latest firmware that’s already been shipping on brand new detectors and now we can all update to it. The new firmware that adds Bluetooth is still not yet released.

My Thoughts

Uniden hasn’t yet posted a changelog for 1.25 so we don’t yet know what the changes are. However, I’ve asked for more detail and will update this article once I learn more.

These R8 firmware releases have been weird. New detectors have been shipping with 1.24 and 1.25. Originally Uniden released 1.23 which was older than what everyone was running and so people who “upgrade” inadvertently wound up downgrading. This firmware didn’t support the new user settings feature in the update software so Uniden later released 1.24 which enabled that feature.

After “updating,” multiple people started reporting that their RLC / speedcam alerts were broken. I’m hoping that 1.25 fixes this issue so that people start getting their alerts back, but we’ll have to see what people report here to see if this is the case or not.

Bluetooth?

The main update we’re all waiting for is getting Bluetooth activated. That is not included in this update, but after talking with Uniden, they said they’re working on a few last things before they release that feature in a future update.

Updating Notes:

In order to update your R8, you’ll want to download the latest version of Uniden’s update software. It adds the ability to change settings from the software. Here’s a quick video about the new update software.

The update software doesn’t yet automatically see, but it should at some point. For now you can manually  download firmware 1.25 from Uniden’s website and load the .bin file into the update software using its “Download Files” option.

It looks like 1.25 comes with the latest RLC database now too so you no longer have to download and install that separately. If you already have 1.25 on your R8 and just want the newer RLC database, you can download and install that by itself.

If you need further assistance with the update software, please read or post in this thread.

    Can the Rj11 plug I use for my V1 be used for the R8 along with the lighter plug power supply? I already have a wire run under the molding of the headliner.

    1. Yep, that should work just fine. I use a V1 hardwire in my car for every brand of RD’s, including Unidens. 🙂

    Thats good…Thanks. I’m also wondering if it can be powered by the USB..The reason why I’m wondering is that Jeep has decided no the have things incars that they have for YEARS…some big and some small. The stopped having GPS in their Uconeect s in some cars as well as sunroofs. The small thing are cigarette lighter sockets. In my 2017 Grand Cherokee there was one in the front centers lower console as well as one inside the armrest. In my wifes 2019 Compass there was one also in the lower console. Now there is NONE, the only one is in there rear seat area in the lower part of the armrest.

    1. Ah yeah, it seems like a number of newer cars are going that way.

      You can always do a USB to cig. lighter adapter if you wanna stick with the cig. lighter cable. You can also run a traditional hardwire and tuck the cable out of sight, bypassing needing to use the USB port altogether. Same thing if you have a powered RVM and use a MirrorTap cable. The last alternative is to get a Radenso DS1 which uses a USB port for power.

    I would only need to figure something out if I were to put in another car…IF I can get that suction cup off of mine. That little 2 suction cup thing shouldn’t be called a windshield mount.
    I have been using it around town so far to compare to my V1G2. I have it set at Auto and town speed limit at 30 and I find I get a lot of K alerts (24.100-24.200 that I never got with my V1, most annoying. Do I have something set wrong?
    BTW…you probably know, but…I was going crazy trying to get my R8 to connect to my computer.
    After doing a Google search I found that the unit needs to be OFF. Counterintuitive.
