Any idea what this might be. While using the Navigation and plugged into the phone, it will initially turn red like it is charging. It will go like this for a while, but eventually it will go from green to red and continue to do so. It still shows the lightning bolt in the battery indicating it is charging, but I am wondering what it is doing.

Mine does this with a cheap wall charger, too. basically the charger can't output enough power, so the phone will start to charge, then the phone realizes that the charge isn't right (wrong voltage/amperage) so it disconnects, then retries, etc etc etc. So the entire time, your phone is NOT charging, at all..
Mine did that while on navigation but no other time, it charges just fine otherwise. and this is on a generic Best Buy car charger
