im having problems with my LXX Xanavi, the onyl lil' prob is the reception in this lil' baby is awful, i've looked for the crippling capacitor in the remote and its not there......it only has a few feet, and then the car tends to have jerky responses to turning, and when forward/reverse is pressed with turning it gets really jerky, this also happens more as the battery dies off...........does anyone know why this is happening and how i can fix it? is it just a bad attenna? any help is greatly appreciated
