Same problem: 1800 is failed. Although pressed Skip on the DAB error - it is not realy skipped and installation fails again on TunerDB. There is also an Abort option which asks me if I want to Abort a spcific device or simpley Abort the whole process. Yet only the abort of the whole is supported. No way to just turn off DAB error or skip it.

Cannot send the SW as they weight high over the 10M allowed. This is the source I have used https://disk.yandex.ru/d/1V1uBTc8ssc3zA I am an experienced tech - so I guess I did the download & unzip well. It also worked fine to me when I upgraded from 0469 to 0741. Troubles appeared only after the next upgrade trial: from 0741 to 1798. Then system shows it is on 1798 but with error. Now, although all versions still exist on the USB stick- the install shield "ignore" now from 0741 & 0742. And "shows" only 1790, 1798 and 1800. Yet, trying to install any one of these 3 versions ends with the same error: seems that something went wrong with install of the tunerDB. And systems stick to last SW version installed (1798)

Another thing i think of is perhaps trying to install 1800 again. But this time to press ABORT (or SKIP) for the tunerDB failure in order for the installation to gracefully proceed and at least support the s23 (giving up the station names but earn the s23 connectivity).But not sure about that. Seems too risky as the HW is not compliant with this SW and i am afraid of unexpected problems. Or simpely I am not brave enought for that

So far seems that only the radio station names are gone (only the broadcast bands are shown). Perhaps it relates to the below message i got when origionally trying install 1800. I guess i can leave with that. Yet my original challenge to connect s23 (which is supported only by 1800 according to other internet posts) seems to have no solution.

Anything else i can do now ?

Thanks for your help.

Unfortunately versions 0741 & 0742 are not noticeable to the system. Only 1790 and 1798 are shown and can be installed. But then the same error is raised in both cases. Any idea for recovery?

Ok. Will try to install 0741 and then 0742. Thanks a lot. Hope its possible after my car shows i am already in 1798. Thanks again

Is there a possibility to downgrade to 0742?

It did install 1798 . But sgain with the above error 9 - unable to find the meta info file

Sorry meant 1798

Is there a way to downgrade to previous version?

VIN=TMBGK9NW1L3069261. Anyhow it did recognized the 1978 but installed 1798 with an error. Not sure how can i downgrade to 1790

At Least 5 times. Specific error is:" 9 - unable to find meta info file". As if something wrong with the download file. Downloaded again and the same problem. Perhaps my source is corrupted. But cant find any other source.
