Help Green then red LED and repeating while on Car charger

[cuban11182]

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.

Thanks

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..

That's what I thought. Guess I need to dump the money for a real HTC charger from VZW.

Thanks

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
