I have had a similar problem before as well.what is the voltage and current you measure coming from your power supply?
Thanks for the suggestion.
I havn't measured it. I will do that tonight. I have tried 6 lithium AA's and 8 Lithium AA's (both energizer brand) connected to the 2.5mm connector. I'm not sure what the mAh for those but they are 1.5v each. I think the current might be the issue. The unit powers on and seems to be working. Sometimes the GPS won't get a satalite fix though. I have heard that can be caused by a power issue.
