Hey all, just got a new GX with the Gen 4 Nav system...I paired up my Razr phone with the Nav with no issues, and while it shows the signal strength of the phone, the battery indicator is blank. Does anyone know of any phones which the Nav system can recognize to show this as well. It says in the manual that not all phones show signal strength/battery levels in the nav...would be nice to know which ones did though...Any knowledge out there??? Thanks!
