GO910 Hard drive to SD Card conversion

What i found is it is not that installing an sd slot turns the go910 to a 710 BUT in fact changing the bootloader as i changed bootloader on a friends go910 in past and it shows up as a 710 and that is using still the hard drive.
Anyway, the cable i put link too, did job perfectly.
Yes the frame is same and sd slot is their but obviously not the plastic housing, and if you try using the frame slot the sd card will prevent it to close as it rubs, as you can see in one pic it sticks reet out.
So simply i stuck the sd to the frame behind screen and all working perfectly.
I used a 4gb card for him as he never used the full 20gb anyway, so no loss their and full Europe maps on their for him to enjoy, fully updated.
Thank you Dave for providing the information, very much appreciated fella.
My dad is well happy as he really did not want the new cheaper built rubbish as he say's lol, and he's right haha.
Here's some pics and many thanks, as i learnt something new.
