Hey everyone,

After long considerations I’ve got myself Lexion LX10S as an upgrade for OEM screen.  
However, since install, I am having issues. The seller suggested to send new harnesses, however even they were changed - the issues remain.  
\- Steering wheel control buttons seems to misbehave: instead of volume up/down or skip/previous track it switches audio source; mutes. All that causes freeze in OEM menu - I can navigate with the cursor, but unable to click anything.  
\- “MODE”, Accept/Decline the call buttons does not work at all;  
\- There is no volume display text when on Lexion screen, although I’ve seen in videos around that it should appear  
\- If connecting to phone’s (which is set as hotspot) Wi-Fi for OTA updates, it causes to disconnect from bluetooth (perhaps it should be normal?)  
\- When screen mirroring from iPhone - it is quite hard to do so, manage to from like 4-5th time by just trying over again.

What is interesting here, that whenever marked harness is disconnected - no issues at all, all SWC buttons work just right. But keeping harness disconnected prevents you from clicking anything in OEM screen menu. 

Has anyone had such issues or might know the reason why they might possibly?
