Wanted to report a weird signal interference near the dashboard. Recently bought a y61 and installed a gps tracker as i always do, everything worked fine. Couple of days after, had the entire dashboard replaced at the dealer because it was in bad condition, they also installed a car alarm and central locking system. After that, the gps tracker had trouble locking a gps signal. First, i tried with another tracker, changed antennas, power cables and still couldn't get the gps signal to lock, so I moved the GPS antenna to sit over the dashboard, at plain sight, instead of below. Didn't work either. At some point I noticed that holding the antenna a couple of meters away from the vehicle, the gps unit worked just fine. This morning I installed a GPS diagnostics app into my phone and every time I had the phone near the dashboard it lost all satellite signal locks, 1 meter away and 11 sats come back. I know about some "gps jammers" devices that sell on ebay to interfere with the gps signal so i was suspicious about the car alarm the dealer installed (maybe it works at the same frequency). I disconnected the vehicle´s battery and still the gps could not get a lock. Finally installed the antenna behind the front grill and got it working for now. In the past years i installed several gps trackers on diverse vehicles and never had this problem. I find it odd that even being near the dashboard with the car battery disconnected there is an interference. Anyone had something similar happening?
