I tried different Apple cables but no luck. It disconnects at different times. I guess we need to see how 8.1 will do

I will try another usb extension cable then and let you know ...

Yes I did and it did not work actually.

After successful upgrade to Carplay with iPhone 8.02 version Carplay works for a while fine with some problems with Spotify but after 10 minutes or 20 it suddenly disconnects and I have to unplug and re-plug to restart Carplay again. It is very annoying. Any suggestions? Thanks in advance

I guess you are using the European version not the US one, right? I have not been able to find the US firmware to download.
