When I got my car two months back, I have to sign an indemnity form with Wearnes to accept that the eco start stop function may stop working once I have the dash cam installed (by Wearnes). The eco start-stop is rather irritating to be honest, and in our sweltering hot weather, i rather have it switched off permanently too.
Like what jemauvais said, the SA told me the same thing about battery management system getting confused, etc. Not sure whether is some lousy excuses by Wearnes or not, as my previous two cars do not have such an issue.
The GPS is rather wonky i must admit, it shows that I am in some grass patches when i am actually driving on the road. Have asked Wearnes to have a look at it when I was in to fix another issue, but they told me that I already have the latest software and updates.
