NEED AUDIO HELP !! HIFI to LOGIC 7 ??
just purchased an 2008 X5 4.8 for the wife ...not an M5 but pretty nice SUV !!
however we did not understand the AUIO OPTIONS And so we sort of got TOOK on that end of it ! sales guy said it was the premium sound assured us that it was the hight end stuff ......... WAS NOT ... I suspect he was just a moron and really didnt know ...MY BAD for not KNOWING MORE ..

So HOW to FIX THIS ??
hoping to just upgrade to LOGIC 7 stuff .. dont mind doing the work if it can be done ....... the car has sirius and the HIFI system ... but I think that is all also it has 2 subs under the front seats

I have already confirmed that the BRACKET for the amp I have and the LOGIC 7 AMP are in fact the same part number


I have the stage ONE BSW speakers on order but they are on BACK ORDER ... so while I WAIT .... may be weeks I can see what else I may do........

I assume there is wiring harness issues and possibly coding to do too .... after the install..


questions:

1. are all logic 7 AMPS the same .. they look so on the outside will an amp from a 740i work ?
2. is the HD radio part of the LOGIC 7 amp box ?
3. is there an UPGRADE harness
4. to have a EQ I need to have LOGIC 7 ?
5. LOGIC 7 is similar to the DSP amp in my 2003 M5 ? fictionally

then there is the whole CCS vs CIS deal CAN you UPGRADE that too ......... we have the 8.8 " monitor ...
I did a search on this and came up empty handed so far

anyone done either of these 2 upgrades ...
