I don't know what i am doing wrong, but everytime i search for something, i got like 1000 of results and even if i choose the specific forum i still get 100 of results. Is there a better way to search on this forum and i am using general terms.. e.g. Some things i am looking for "screen protector" i wanted to know if those screen protector sold on ebay for $12 really can work making the screeen little safer from scratches etc...also wanted to know whether the Z2 remote that mounts on steering wheel is wireless or have to run a wire to Z2. So i type all kind of things like Z2 screen protector, screen protector, z2 protector etc but still got too many results and no specific thread dealing with this questions....Time to fix the search feature on this forum i guess.....

The wireless control for the avic-z2 is CD-SR1, yes it is wireless. For the screen protector I recommend you to buy it from navscreen on eBay,

I’ve purchased some cheap one before and some don't fit or won’t stick.
