[A4] Help: Installing a Bose Symphony head unit in a non-Bose A4

Hello from a long-time lurker and infrequent poster.

I own a 2000 A4 1.8T Avant with the non-Bose Symphony head unit. The CD
player went dead a couple of months ago (very common, apparently), so I just
bought a used Symphony head unit off eBay (same part number as mine).
However, it appears that the Symphony unit that I just bought has the "Bose"
option (it displays "Bose" upon startup). So, I'm having compatibility
problems (only the rear speakers work). Here are my questions:

1. Is this behavior (only the rear speakers working) expected if you install
a Bose Symphony unit in a non-Bose car?
2.If so, is this because the "Bose" cars use a seperate power amp for the
front speakers?
3. Is it true that I can re-program (using a VAG tool) the Symphony head
unit that I just bought so that it will NOT use the "Bose" option?
4. If so, how do the front speakers get power in a non-Bose system? From the
head unit itself?
5. What should I expect (in terms of price and attitude) from an Audi
service department if I ask them to re-program my new radio?
6. Does anyone have any recommendation as to an independent shop/mechanic in
the Boston area that can reprogram my new radio?

Any knowledge and experiences that people can share would be greatly
