hey Rons and everyone everything i believe its the cheappo sd is the problem... its probably due to my cheap sdcard that i been using... thank you rons
just to a side note
I was having issue with bluetooth that's the main reason I updated... when i was on map2015 update it worked for the first few months and then all of a sudden it stopped streaming music over bluetooth. My first assumption was its because I updated my phone... few phone update later still having the same problem.... I'm using samsung s7 with my x930bt.. fast forward last two nights i was bored and looking for a resulotion. for 2 nights I been looking for an older version of bluetooth firmware. older than 3.24.. since i couldn't find one. i was like hey try updating again since i came accross this update... i tried it last night using map2017's bluetooth. since thats the only thing i can do using a crappy sd...... that didn't... so finally this morning i was able to update the main software and map.....tried updating the bluetooth again with the same result i cannot stream music over bluetooth... then agian.... i was hey one more bluetooth update.. it should hurt... finally it work... so i guess you just have to keep updating bluetooth untill it works.. maybe the update is not sticking for one time try.... I'm i might be just crazy anyways.. now i left a copy of bluetooth update on my sd just incase i have the same problem again later on.....
another qick question ... seems like the x920 x930 x40 has more update or hacking thank x950... is it worth buying a x950 second hand??
thank you Rons and the 411 forum...
