Tried to fix my wife's (2008 is250) navigation over the weekend. Long story short i failed and gave up after hours of trying to get the copper circuit exposed. Put everything back and what do you know i now have check VSC, and AFS OFF lights in dash. After further investigation i realize key fob will no longer lock or unlock door (and lock switch on panel only works when car is started). also, if i put the car in accessory mode then nothing lights up in dash. Fob starts car and once started seems to run fine but have the VSC and AFS errors in dash. Took car to autozone to check codes and they say there aren't any codes thrown. what could i have done and what should i do. Planning on heading home and checking some fuses after work. any ideas????
