Hello.

SD card removed by mistake and lost it.
Now I can't turn it on... formatted 2 micro SDHC cards to FAT32, tried with FAT16 too.
One in front panel, second in rear side of radio.

It still says ,,Check SD Memory Card. Please see the owner's manual in details" (did it, manual can't solve it),
can't turn it on.

Is there any special boot for that? Or what can I do?

Please somebody help me.

Serial no. is QZ-3020E-A 0000476
Exact model FX503EAIXAM-13
Type 9954223
