Thanks for your reply. Yes, I bought Z110 and just wanted to update the software and maps. I wasn't going to bypass the unit and really confused why it's saying that parking brake is not connected and why it falls into a test mode. 

^{Need  Help. I bought my Z110 on ebay. After I properly installed it, I noticed that it keeps saying that the paring brake wire not connected. However I connected light green wire to the parking brake. All the feature are active like address search and system setting when I'm on parking break. After I inserted Miscro SD it tried to start update and then falls into a test mode. No matter what I pressed it stuck there and nothing happens.}
