We have a massive problem with the IVI hands-free system in the brand new Zafira electric Facelift.The participant calling from externally into the car always hears an echo and can understand the conversation very badly – whether iOS or Android – no matter if only CarPlay/Android car or only Bluetooth – no matter which side initiates the conversation The FOH is still completely perplexed. Otherwise the Facelift is very successful! May occur with several vehicles – but not with the Vivaro transporter? Softwa Is there anyone else who knows the problem? What software version do you have? With us he shows 1.27.52.4. But should there be more?https://www.opel.com/tools/oss-source-codes.html
