1. Check ebay for a replacement face. The way Alpine's are, a different model # may still work worh your deck.
2. You can use your stock deck, but then you'd have to also use a line-level convertor for the RCA connections due to the fact that the stock deck does not have rca jacks. Also, sound quality will not be as good as with the Alpine.
3. Again, check ebay if you wanna go cheap.
Lastly, please remeber to take your face off next time. :thumbup:
