Mio QuickGPS is easier to use on other devices I think as HTC QuickGPS seems protected (it didn't run on my Mio A701 ; first I had to transfer the files in a zip as a direct copy/paste was not possible)
I Don't know if AGPS will works on other devices, thought.
All we have to do is run this app and download the latest calibration file?

Hi, Happy New Year to all! Noone any solution? Mio company will have a solution, any other user with same problem with me???????
No solution, same problem
Hello Sakisgr,
Sorry I don't have a solution for your problem.
I have the same problem and no solution yet.
My first problem with my MIO P550 started because some programs would not run caused by to little memory.
That was the reason I executed the "LowLevelFormat" command.
After that I also executed the "Mark Bad Block (50MB)" command
After that i did "Image Upgrade Tools" "Image by SD/MCC"
and flashed a downloaded firmware Win 6.1.
After that I have a running machine but 50MB memory missing!
Can I get my 50MB back ??? how ????
or do I have to buy a new motherboard with memory and win 5.0 ???
I want to flash to Win5.0 NL ( my origional version)
does anyone has a .bin to download ?
Thanks in advance

Dead Mio P550
I had the same problem about a year ago. It took some time to solve it but finally I succeed. Here is link to the solution - but I warn you it is in polish. Maybe You find it useful. On the other side - mainboard for this Mio costs in Poland about 30$. Answer yourself whether it makes sense to repair it ...

Mio C720 jTag

My Mio C720 stuck on orange logo Mio Screen and WinCE can't boot up (after that screen MENU must appear). USB communication doesn’t work.
On some forums I have read that I must do jTag (or some other kind of flash ). On GpsPasSion forum I found ROM from working C720 device, but there are no tutorial how to flash it.
I would be grateful if someone can help me with this (jtag schema, using tools, tutorial...).
P.S.
There isn't problem in navigation software. Device can work without navigation software.
Thank you very much and sorry on my bad English.
P.S.
Done.
