Help required in playback and radio station setup in Alpine head unit

Hi all

I have installed Alpine CDE-100EUB/CDE-100E head unit for my new car. The problem I am facing is that when I switch off my car for say 10 mins and start it

1) the music system doesn't starts automatically as it happened in xplode of my old alto.

2) I gradually push the source button to the usb selection and it starts with the 1st track of 1 folder. It should have resumed from the last song played I presume.

3) The radio station gets reset and i have to configure all the stations again.

Please note this happens when i switch off the power of the car for a couple of minutes. Is there some setting I need to do to resume playback from usb everytime? Anybody else had encountered some problem like this.

Any sort of suggestion would be appriciated. TIA

Regards,

Sudeep
