Advice on Aftermarket Alpine stereo for Audi A4 B7 - FM RADIO!?!
Im new to this forum and I am seeking some advice!!!
I recently had my Audi RNS-E system pinched from my car Audi A4 2007 (older shape).
I decided to replace it with an Alpine CDE-114BTi. I got all the necessary adaptors etc and fitted it successfully apart from one thing... :scared2:
The RADIO! I cant seem to get it to work... I have used a Celsus AA2134 Dual fakra antenna adaptor, I have connected the blue wire from the antenna adaptor to the switch live wire. It picks up MW fine however FM is not clear and I am not picking up all stations... :wacko:
Please can someone offer some advice it would be much appreciated?!
Similar issue when using fakra to DIN adapter - noise when I turn on lights
Not a solution I'm afraid but some additional information/questions as I'm experiencing a similar issue.
I also have 2007 A4 that I have replaced the head unit for a JVC double DIN unit (KW-XR811). This has the standard DIN aerial socket and the removed Concert stock HU had the dual fakra, so I bought Dual fakra antenna adaptor (tried with and without the inline power thing) but in both cases, when I turn my lights on I get a whining noise (side lights and main beam, and with the engine off).
If I pull the aerial lead out, the whining stops.... if I turn up the volume, it's less noticable but still there.... if I drop the volume to zero, it stops so it is somehow being introduced to the HU and that's outputting to the line out to my Bose setup.
Also, looks like I'm picking up about 3 stations on FM -- Radio-2, and two local stations -- nothing else.
The aerials are wired into the rear side windows.
Questions for Alan -- do you notice any noise when you turn lights on? Also, what type of aerial do you have.
Has anyone replaced a head unit where fakra to DIN is needed and had any issues?
I tried running a jump lead from battery negative to the radio case -- no difference. What did improve slightly was connecting the jump lead to the ground of the fakra twin socket where I plu in my twin cable adapter that then goes to the radio. It just seems to me that adapter is picking up the noise..... or, the aerials fitted to the side windows aren't really suitable.
I tried disconnecting the earth from the aerial lead plugging into the radio --- whinning sound gone but radio reception even worse..... so my issue has got to be the aerial lead in some way. Obvioulsy plugging the aerial into the stock Concert HU it works a dream.
Any other suggestions welcome -- maybe I'll need to fit a roof aerail and cable in new?
Thanks -- sorry for waffling a bit and jumping on Alan's post but seemed similar to my problem although the whining not reported.
I have ordered another fakra to DIN adapter tha has no cable --- although this'll only connect one of the two aerials, it'll remove any cable issue between the two connectors as there isn't any. I should have that in a couple of days and will report back.
