I agree Dasil. And you'd be aware from other posts of mine going way back that i'm an advocate of putting everything possible on sd. However, this 1490 owes me next to nix and accordingly i've used it solely for experimentation. If i brick it, so what? The mount, screen, case and battery are worth more than what i paid for it and it came with a GTM26 traffic receiver too. Although if i did brick it i would probably bite the bullet and reflow the usb connections 'cos that's what's wrong with it. It charges if i tape the charger lead to the back of the unit to put a bit of vertical stress on the usb header, it goes into msm for 20 seconds and then boots normally and will navigate perfectly as long as the tape holds fast. In fact it will stay in msm [or enter pre-boot] connected to the PC by putting gentle and steady sideways pressure on the header as well. However, the pressure must be maintained consistently and it's just impossible to do updates that way without a second pair of hands. I bought it on ebay from a guy who bought it in the States while on vacation. It was one of Garmin's refurbs in the blue and white box, cosmetically it's in pristine condition and the battery holds charge well.
