Raz407 Posted April 24, 2017 Report Share Posted April 24, 2017 Hi guys, I've searched literally a hundred threads and I'm still not 100% sure so I'm hoping someone who has done this already can enlighten me. I have the newer model antenna in the e46, this is the one without the additional fakra power connector and I also have an aftermarket head unit. I get pretty bad reception and from what I've read the antenna is powered down the coax and needs the adaptor in the link below to feed 12v power down the coax to turn on the antenna amp. I found a harness diagram and I can see that pin 16 on the harness is "Turn-on (antenna+amp)". Problem is that I came across a thread where someone said they fed 12v to pin 16 on the harness and this resolved the issue as the amp is already on the loom and required power? Doesn't pin 16 output 12v to "turn on" and this is what I should be connecting the blue power wire to on the adaptor below? I guess what I'm asking is pin 16 a 12v output to turn on the amp or a 12v input to turn on the amp and if its an output will the adaptor below when linked to it power my amp? http://www.ebay.co.uk/itm/VW-TRANSPORTER-2003-ONWARDS-AMPLIFIED-FAKRA-DIN-AERIAL-ADAPTER-LEAD-POWER-/401140685284?hash=item5d65d919e4:g:6jIAAOSwc1FXZ~Fm Any help would be really appreciated, this fuzzing radio is driving me crazy Link to comment Share on other sites More sharing options...
lozevans Posted April 24, 2017 Report Share Posted April 24, 2017 Pin 16 is the power to amp, connect blue wire from head unit to it, should sort problem Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Raz407 Posted April 25, 2017 Author Report Share Posted April 25, 2017 Thanks for the reply lozevans. Just to confirm is pin 16 already live with 12v and I should be attaching the blue wire from the fakra adapter to send power over the fakra coax or should I be sending power to pin 16 from the amp power out on my head unit?

dontpannic Posted April 25, 2017 Report Share Posted April 25, 2017 Do you have a facelift E46? If you only have one Fakra connector behind the radio then the power for the antenna amp is at the antenna amp rather than piped down the antenna cable.

Raz407 Posted April 25, 2017 Author Report Share Posted April 25, 2017 Yeah dontpannic, I have the facelift e46 with the one fakra cable but read somewhere that you need to send phantom power down the fakra using that ebay adapter to turn on the amp. Lozevans, I'll see if I can get the amp control cable from the aftermarket to pin 16. Not sure where its going already as its part of the after market plug so its probably feeding the wrong pin at the loom plug , I'll have to take look after work and update. Thanks guys Link to comment Share on other sites More sharing options...
Raz407 Posted April 25, 2017 Author Report Share Posted April 25, 2017 Hi Guys, Just a quick post to say thanks for your help Checked again tonight after work and now that I know the head unit/ loom plug pin positions I found that the amp out on the head unit was already going to the amp/antenna pin 16. Was stumped for a short while and got the multi meter to check it was in fact sending power, which it was? I was going to check the fakra antenna back to the amp for continuity and as I was moving the connector I have full signal!? It seems I have a break in the fakra to din adaptor cable so if i hold it in the right position to touch the breaks together I get full signal. I could have spent ages testing everything so quite lucky really. Someone must have been a little ruthless trying to get the head unit at some point as its a tight fit. Gonna go get a new PC5-100 adaptor tomorrow from the local car audio place and finally have proper radio! Thanks again Link to comment Share on other sites More sharing options...
