I actually had a newer MCU version (M:221228V1) but went ahead and applied the update anyway. Process went fine and it seems to have resolved the connection issue. Thanks for the info.

Anyone try the update on this Isudar version?

Westcoast

Isudar recommends that you get any software software updates directly from them... have you asked?

leedo3

Yes I have. I received an update from Kimi in April 2022. There was a newer update that was released in July 2022. I requested the update from Kimi in August, but have not heard back from Isudar.

Westcoast

The update that I applied was to correct the issue of the Isudar board remaining connected after the vehicle was turned off... Was your update a full system update or a specific fix?

This July update, what is it for, or why do you need it, is something broken or not working properly on you Isudar board? How do you even know there is one?

leedo3

Strap me to a chair and shine bright lights in my eyes.

Update was to fix a intermittent dropping of connection between board and phone.

Kimi was the one who informed me of the July update, but no specifics.

Westcoast

Ahhh, OK?

Your screen shot shows a different hardware version (2.0.0.B) than the latest (S7.B), this might have addressed the dropped connection, but did you try going to 2.5GHz instead of 5GHz?

My board came with version M:220708V1 out of the box and the connection was stable, perhaps because of the fix you mention.

You all make me laugh updating firmware when no issues exist. I guess that’s what you think is needed….

FYI, ensure AuxBluetooth is NOT used by w these units. If you so, you’ll find the audio will stop very shortly after starting the car. You’ll need to restart the PCM. Only need Aux.

Updating the FW corrected my last and only issue with the board, unit staying connected to the phone when car is shut down. Not sure what you're on about but welcome to the forum!!

I've this problem with sound after start car on Mr12Volt card. But it's only spotify and it's not necessary restart PCM, only choose read on the screen
Where is modification Aux ? Thank's

Hello everyone. Need some help, please. I have the iSudar version 2.0b in my ‘14 CS that was working ok, until I tried to update my firmware to address a volume inconsistency issue. No I have no sound. It’s set to aux input… I’ve had the unit about a year, but the inconsistent sound was making it hard to use, so I tried and failed to update. Kimi replied to an email, but I didn’t buy it from them. I bought in Amazon.

I spent a few hours go over this whole thread. All 86 pages. I just really need latest firmware p, if some kind person can help me out. Also, MCU update (not exactly sure what that is, tho).

Thanks in advance.

Westcoast

Sorry to hear about the problems but you shouldn't update the firmware unless you know that it is compatible with the hardware and firmware that your board uses, randomly applying such update are not necessarily going to fix the issue and mat result in a non-working board.

What did Kimi say? Do you have screen shot of the versions, both hardware and software?

There was a F/W version that was wacking the AUX. The new file is out now, and fixed the problem.

Westcoast

And do you have this file and what version of firmware was it for?

Willy07

I have the original 1.2 board. I recently applied it to another board as well, that did not come directly from isudar.
