Need Clarification Regarding HD Radio

[jim628]

Hi:

I have the following questions regarding BSW HD Radio for E53

[1] I have been reading several postings and still not sure that if I buy
the Dice HD Radio from BSW for my E53 with standard (no upgrade,
no DSP) sound system, do I need to run extra wires from the back
of the car to the stereo / radio console in the front? I assume the
HD unit must be installed in the back of the car where the CD changes
is supposed to be.

[2] Where is the HD radio antenna located?

[3] How is the sound quality. From what I read, some owners complained
that the radio is picking up electrical noises.

BTW I have 2006 E53.


Thanks,
Jim
