jamesfoley Posted November 16, 2016 Report Share Posted November 16, 2016 Had my car for just over a week now, and I can't figure out why my android head unit doesn't seem to have an FM signal at all. Do these units not have the correct wire for the remote antenna power? Car has just the single antenna connector rather than two with one of them being power. Anyone able to point me in the right direction? Quote Link to comment Share on other sites More sharing options...
RMJ Posted November 16, 2016 Report Share Posted November 16, 2016 I believe you need a signal amplifier to help it pick up clear FM waves mate, got one with mine but never listen to the radio. Quote Link to comment Share on other sites More sharing options...
jamesfoley Posted November 16, 2016 Author Report Share Posted November 16, 2016 Ah so something like this? http://www.ebay.co.uk/itm/PC5-136-BMW-Amplified-Fakra-Aerial-ISO-Adaptor-/290627388575?hash=item43aabe049f:m:mUx4J7cIA1A3YvK4SGIHPMg I always thought that the antenna had a built in amplifier in the C pillar and that it took power from the loom?

TriggerFish Posted November 16, 2016 Report Share Posted November 16, 2016 I have this problem too - it's also roaming between stations too. The only thing I could pick up consistently yesterday (flat phone, no bluetooth) was ClassicFM! For £3, I'll give one of those a try. I thought that it was amp'd in the c-pillar too, though.

RMJ Posted November 16, 2016 Report Share Posted November 16, 2016 That looks identical to the 'booster' I have Like Joe says, for £3 its worth a punt! Quote Link to comment Share on other sites More sharing options...
dontpannic Posted November 16, 2016 Report Share Posted November 16, 2016 It could be your cars inbuilt amplifier giving problems. I had to replace the side window antenna amplifier in my Touring. If your ISO to Fakra antenna adaptor has a blue wire, hook that up to the antenna power on the ISO loom as well, there are a few different configurations of antenna systems in the E46, some need extra power, some don't.

jamesfoley Posted November 16, 2016 Author Report Share Posted November 16, 2016 I'll pick up one of those little powered amplifiers and give it a go. I don't really use the radio much to be honest, but its just the fact that it doesn't work thats bothering me Quote Link to comment Share on other sites More sharing options...
jamesfoley Posted November 29, 2016 Author Report Share Posted November 29, 2016 Just thought this was worth a quick update, I ended up ditching the android headunit due to sound quality, but found that supplying 12v on pin 16 on my radio loom powers the antenna and I get flawless FM reception. In this case I just piggy backed off of the sub remote on the headunit. The_Judge_, TriggerFish and RMJ 3 Quote Link to comment Share on other sites More sharing options...
