Garmin Oregon 450 External Power

Followers 1

Recommended Posts

I just received an Oregon 450 and I've been trying it out. When I plug in my external power cable the unit enters mass storage mode even though it's just a power cable. I have two power cables and it's done this with both; kind of hard to drive down the road in mass storage mode. I thought I remembered someone else on the forum having the same issue but I can't find the post. Anybody know what the problem is or where the previous post is?

It will work in this mode:


Setup > System > Interface > Garmin Spanner.


I think you'll have to do it this way unless and until you purchase a 12v cable made specifically for your Oregon.


Additionally, you have to set that to Spanner in each profile you are likely to use the handheld on external power.
