I don't know, my car is Mercedes Benz ML320?

My F-500BT normally take about more than two minutes to get GPS signal and sometimes lost signal, I did hardware and software bypass (using testmode, thanks again), everything working fine, just has trouble to get GPS signal ( that happened when I get this unit from 6th eve.com and has Version 2.000 on it) I tried hard reset, not help. Please help me if somebody has the same trouble and solved it. Thanks advance. HPDANG
