I have the xdvd710 when i start my truck up volumn is blastin every time!!!!! how do i get it to stop?????

The dual XDDVD710 RADIO has a volume memmory (it seems), it will go to the last volume setting that it was set to, not play to,(supposly to keep it from blasting you when you turn it on and you forgat u had the volume on blast).
To set it,
1 turn radio on,
2 turn the volume to desire Level you whant it to go when you turn it on (other Levels besside BLAST hopefully) ,
3 push the volume button in, that should do it.
Now you can play your music loud and should you forget that you had it on BLAST (to over come road noise) when you last played your radio, it should start at the preset volume.
