Hi, is it possible that this is a problem with the speed sensor. When i start, i can see that the speed sensor is not recognising the speed correctly till about 25mph then it kicks in. Where did the speed sensor sitting? Thanks Pierre

Hi, Problem is to find some one in Germany wo want to touch those cars. What confused me is that its not happening all the time and what i saw in the data is that the pedal position is stady but the throttle position is dropping, which makes no sense for me. Also some information which i missed, is the car was staying for 10 days as i had contact to a person who had Covid, so i didn’t left the house, when i parked the car, all good and after that it started. Thanks Pierre

Hi, after a while i have now again a problem with my truck. I will try to explain what the problem is. if i accelerate from stop to 35mph, the rpm start going up to 1200 and then there is a hard jump about 200rpm to 1400. This only happens from stop, not from slow speed. I had this morning a problem which disappear but the speedometer showed the wrong speed till 25mph and then it jumped up to the right speed, while i had this problem the transmission worked okay, after work started the truck and the RPM jump is back and the speedometer is correct. I am not sure, if its a engine or transmission problem, there are no dtc in the truck. I am happy to get some ideas what the problem might be as i am stucked. Thanks Pierre

Thanks for the feedback. What did you think could happened down the line? And what would a custom cluster cost? Thanks

so i can share my experience. I had a HMI out of a 2016, I updated this with a 2016 vin plus lates update – I didn’t got the app store and WIFI, as my Radio Module came out of a 2017, I also updated the HMI with a 2017 Vin, I now have the app store and wifi in my HMI. So it looked like some of the functionality is only available on certain models and not for all of them. ALSO I need now some help – everything is working, I can hear siri, which is fab, but how can I answer calls in carplay, I cant do it via the steering wheel buttons or I didn’t found the right button. Also did we found a way to get Siri Activation working? Thanks Pierre

Hi, so small update from me, I installed my radio module and programmed it with the gm sps. The trick is to use a vin from a 2016 or 2017 Silverado. So I got everything working. did someone find a way to use the Siri voice button? thanks pierre

Hi, I got my USB port and hmi module. I was also able to update the radio and hmi to the latest version via gm sps. So every thing is working except from Siri is not talking...... so I had the text app in the old hmi, but just the radio update doesn’t help. Has anyone an idea or did I need the radio module? Thanks Pierre
