When your at a light and it drops voltage, then picks right back up when you start driving again, that tells me that your drawing power.. For your radio, is it a stock radio or do you have the whole setup with subwoofers and what not. The GPS shouldn't be affecting the voltage too much. My F250 did the same thing, I bought a new battery with higher CCA, voltage. It overall was bigger, but never had that problem again. For your radio, if it is the whole setup with the subwoofers, go with a capacitor.
