Re: Autologic, I have never tried it, but if you go to retrofit section and go for the option of adding hi-fi amp/ sound system, it should do the trick.

I remember reading somewhere that bussiness navigation is not easy to code to hi-fi but not sure how true is that.

I have mostly done professional HU, professional CIC/CCC and only one bussiness navigation so far.
Hi there,

Ok, it would seem that the only retrofit /upgrade option displayed on Autologic was Top Hifi /Logic 7. He did go ahead & pushed this update in & the car accepted it no worries. After the update there was no sound at all. from this we deduced that the Top Hifi /Logic 7 update requires the L7 amp & diverts the output to the MOST bus on the HU?

DO you guys know if this means I will defo need to upgrade my HU to CCC instead of the Business unit?
