diagnostics/maintenance mode on nuvi 250 and other crapola
Yesterday (which was about 15 minutes ago being it just passed midnight as I write this) I picked up sis from TPA and delivered her to Pop's. She'll be there until Tuesday where I have to pick her up again and deliver her back to TPA so she can fly home.
She is well just in case you're wondering (as is Pop). 🙂
I asked her to bring along her nuvi 250 so I could update it. After bringing it home I ran the updater and yeah, it needed it.
In addition I found out that in order to get into the diag mode you have to press and hold the on-screen battery indicator for about 7 seconds and not the exact top right (which is the case on the c580).
There's a little trick to plug in the unit via USB and have it not go into standby mode.
- Boot unit.
- Go into diag mode.
- Plug in USB cable.
- Exit diag mode.
Unit will reboot into normal mode and not standby at this point.
Why do I bother with diag mode? The answer is so that you can work with the unit while connected via USB when you upload point-of-interest stuff. Otherwise you send the POI stuff, unplug USB, reboot unit, blah blah blah. Wax on, wax off. Pain in the ass.
When doing the diag mode/reboot trick you don't have to do any of that. Speeds things up a bit when you're trying to get things done.
