21 Infotainment V155 Update


Recommended Posts

Went to the dealer today and requested that they preform the V155 update, When I go into the menu to the about screen it shows the March 2020 version but below under the update history nothing is shown to confirm the update has been preformed. Should the V155 update appear under history. 

Thanks

Did the dealer do the V155 under warranty? I have a 20 that will not connect consistently to CarPlay or Bluetooth. I know V155 is supposed to be for 21s but I asked about the update and was told it would be $145. I contacted GM and they confirmed. 
 

Another dealer tried another update that didn’t make any changes and has since told me about TSB 21-NA-145. Anyone know anything about that one?

I asked for it but I have no way of knowing if it was done as it does not appear in the update history. That is my question. I suspect that they did not do it.

My truck is loaded with V153 could that be the issue?
