I have an 05 1SB and just had my system upgraded. I added a JL amp 500/5 and new Boston Acoustic speakers in front and rear. They sound great, but now when I look at my Nav screen it can't identify my accurate location. And on the left upper corner there's a GPS icon that has a line through it.
Since my car battery was disconnected during the install, is there something I need to reset in order to make my Nav work properly? I've already ejected the nav DVD and reinserted, but that didn't seem to change things. Thanks for your help.
