I have a alpine 7897 deck and it was working great for 4 months and now when i turn on my corvette it opens up and powers on and displays the word interrupted and i cant do anything just look at it...can some one help.....
THIS IS CAUSED BY AN SHORTAGE OF POWER TO THE UNIT. IF THE UNIT ISNT GETTING THE REQUIRED AMOUNT OF VOLTAGE IT WILL SHUT DOWN TO PROTECT THE UNIT. THE ISSUE CAN BE FIXED BY PULLING THE UNIT OUT AND DOUBLE CHECKING THE 12V CONSTENT WIRING TO MAKE SURE ITS NOT LOOSE. IF THAT DOESNT SEEM TO BE THE ISSE THEN ITS A INTERNAL ISSUE AND WILL MOST LIKELY HAVE TO BE SENT IN FOR REPAIRS. SO FAR I HAVE DELT WITH 3 OF THESE ISSUES ON HAND AND ITS ALL BEEN LOOSE WIRING.

could be a few things-pull the unit out and make sure the power and memory and ground wires are all solidly connected.check your fuses may be a little tiny one inserted into the back of the deck itself-check fuse box also. if you still cant get it to turn on get a volt tester or test light and make sure that you are getting power to the deck.
On some units you have to hold in the selection button for 3-5 seconds. This should bring you to a menu that allows you to change bass power and your tremble. Also on some units you will find fade balance in this menu as well.
I have the same deck and a very similar problem. Mine was stuck in the out position and would beep and move a little but there was no lights or music. I called Alpine and they told me that sometimes the inner sleeve around the deck will pinch the unit a little. I took my unit out of the dash and sure enough the plastic face plate came loose and moved about 1/32 of an inch when I slide it back in place and turned the power back on it worked perfectly. Hope this helps.
the alpine should recognize it as a "changer" when you select the source; ie: radio, CD, changer. Sounds simple, but have you turned up the volume on the iPod?
The Alpine adapter is $100, but works great, you can totally control all your iPods functions, and it displays all song info on the Alpine decks display.
What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go.
