Well.. I installed another z110bt and did not even hook up the break wire.. and still.. The same mesage popped up on start up.. Wire in hand..lol... Today I will be calling my tec guy .. I will let you guys know what it is..

Right to the "E" brake... and when I check the connection screen.. the parking break goes on and off when I pull it up and down...

Hello everyone.. I am a installer that has been installing the new Z110bt for abit.. A customer told me that the parking brake warning screen always displays when he starts up his car.. even if the brake is off...I thought it might have been a bad connection..but Today I installed a Z110bt in another car and the same thing happened.. Is this feed back on the line or is there a problem with the new units.. can anyone tell me.. Thanks..
