Will test tonight (well go and sit in the car and have a play with the leads).
On the subject of battery life, you may find reducing the scren prightness helps to extend the time, think I have mine on quite a low setting and it seems pretty good.
By the way, is it me or is the unit a lot louder when on car power, more testing required I suppose.
Will report back later.
Andy

I'm using some 2700mAh NI-MH's and it lasts about 7 hours before it stops.
That's with full screen brightness and vol on 5.
The batts were of eBay HERE for anybody that's interested.
Total £10 for 8, but don't forget you need a compatible charger. |

Just bought the garmin i3 today and found that it has a battery type selection in the system menu, anyone know why?
I also noticed that while plugged into the Mac (with virtual PC, role on OS X support) that the 2300 NiMh batteries I've installed appeared to have more charge... suggestions?
BTW Hi folks, first post |

So the battery meter can read the charge from the battery correctly.

An illusion. The i3 has no charging circuit. How did you find out they had more charge? |

 to the forum's .....
Standard LR6 (AA) batteries are 1.5v, but rechargeable's are only 1.2v so it uses a different resistance to measure them. |

That's because the i3 is powered from the USB when it's plugged in, not the batteries.
