hi all could any body tell me what the white .05 wire on pin 13 on n9 to n8 antenna amp purpose is ? (pic below) because in wds the antenna amp has a live feed from fuse f53

iam thinking its a live from when radio is on to wake up the amp

as my extron unit does not receve fm very well at the moment when the black antenna lead back of dash is pluged into it





i have also posted in e39 section

sort of heageing me bets :)

The OEM antenna amplifier units do need to be operational in order to send a good/decent radio signal. If your's is connected and working properly and you still get poor performance for FM/AM reception, then the reason is most likely the poor quality of the Tuner stage within the head unit. Getting a head unit that uses higher quality electronics would be the answer !


Cheers, Dennis!

thanks dennis

i have been doing some reserch on this problem and the antenna amp needs to be powered up like a audio amp, well a turn on signal like audio amp anyway.

its the white wire as per wds. i know the main power feed (f53) is ok as this also does the rear tailgate  and thats ok  so iam just gonner make sure i have a turn on feed from  head unit first .

i have been useing the dab unit but the reception on dab is  vairable at best

this is not head unit related

i read someware if you feed 2x dab aerial feeds from front and rear this can inprove things a bit

i like the unit i got but as said in the other post on android  units the 600+ quid american unit looks good but iam not sure if its that good

i will have a think about what i realy want in way of audio,  i dont use sat nav much and any way

i have a standalone unit i use in van so not a problem is needed

so maybe a high end single din is the way.
