Navman S80

hello guys
i really need your help with this one,
I have a navman s80 in perfect shape but with few maps on it's original software so i figured i can do something to load mio or igo to it.
i load mio on flash disk and i change the appstartupsec.ini file so the first process to be mio but now it runs mio for a few seconds, then run smart st gps and restart.Nothing further.The thing is i can't access any memory now, it won't connect with PC anymore to reverse to original file.What should I do??????????Is there another way to access flash memory?
Please, i need urgent help !!!!!!!!!!

All-in-one devices will only run the manufacturers software.

Sounds like you'll need to try and get it repaired.

is there a software that would help me to restore the operating system ??????
