Hello everyone, I enjoy reading about maps and gps units and have learned a great deal here.
I just bought a Garmin astro 220 and love it for tracking my dogs. I can power it by the usb cable that came with the Garmin from my computer so i was wondering has anyone tried a blackberry car charger as it has the same end as the usb cable that came with my Garmin. I tried charging my blackberry with that cable and it works. I was a little afraid of screwing up so i thought i would ask here and maybe get an answer from someone who has tried it. Thanks in advance.
where are the specs for the astro? I am not doubting you but would like to know for sure because my manual didnt list the specs for external power. sorry i am being difficult but i am cheap and dont wont to have to buy something i already have.
Great links. Do you think Chinese import charger can be trusted in a 12vdc to 5vdc?
again thanks for link
Transformer might even be overkill; I've built my own with just a voltage regulator which was like $2 at radio shack :)
The biggest problem you may have is that it'll go into computer mode (mine has done that with certain usb charging cords, no idea why).
