Hello,


First: I'm sorry for my bad English writing Now my question..

I own a Garmin Oregon 400t and now I was wondering if it is possible to get software or
firmware (for example) a 450t or even 550t on my device. Don't know if this will
work , and of course i know that there will not be a camera on my 400t by upgrading
it
Does anyone know something about this?

And another question about my oregon 400t: there is by routing a sound (beep) for each
waypoint. Is it possible to make this louder?

Thanks people!!
