Alright! Good choice..I recently had a Eclipse head unit put in my 1999 C43.It does have the security code feature that you can put in yourself. My Headunit also has the 24bit and it makes the CD sound very good.Most other Head units I think are around 1bit.
I love the Eclipse though it may be a bit more complicated to tune...at least for a layman like myself.Im sure Pros like Scott at Lajolla can navigate their way around it very quickly.
