Cressa 44 Posted April 8, 2020 Ok, this question is for future proofing. I have a Hitschmann DAB aerial that I used on my Golf GTi Edition 30 and was considering putting it in the Corrado. As I have no trim in it would be easy to route some cables at the moment. Just a thought 💡 Would you do it ? I'm so covid bored obviously Quote Share this post Link to post Share on other sites
seanl82 23 Posted April 9, 2020 The antenna looks stock so for me, it's a good upgrade and allows far better options as you can fit 'retro' looking radios but have modern functionality. 👍 Quote Share this post Link to post Share on other sites
fendervg 33 Posted April 9, 2020 Looks the part - will it still give normal FM reception? Would work great with the new Blaupunkt DAB retro unit. Quote Share this post Link to post Share on other sites

Worked totally fine before so I have no reason to doubt it now. I just need to search for some wiring. It did have a fakra connection added to it, but I dont think I need that for an old VW Edited May 31, 2020 by Cressa Speling correction Quote Share this post Link to post Share on other sites
easypops 8 Posted April 9, 2020 I’m interested in fitting something like this as well. I guess it’s gonna need all new wiring right back to the radio? How about power? Do you use that blue wire at the back of the radio that never seems to get used? Quote Share this post Link to post Share on other sites
fendervg 33 Posted April 9, 2020 There should be power to the stock aerial anyway - it has a little pre-amp in the base and is driven from the head unit - think that is the blue wire, yes. You'll see this wiring clearly if you pull the headlining down a little at the rear to access the aerial base from underneath. It earths back through the bodywork.

1xshaunx1 27 Posted April 9, 2020 Unfortunately not all were powered, if the first photo is of your original aerial it’s not powered. Quote Share this post Link to post Share on other sites
Cressa 44 Posted April 9, 2020 The base isnt powered as Shaun says. There is some kind of powered inline booster to the aerial behind the stereo Martin, I intend on running a DAB lead alongside the other via the passenger A post and roof. Plenty of different connector adaptors, but it would be nice to get the correct lead. Shame they mainly seem to be 5m long...shorter would be nice For the power I was thinking of running this on the opposite side to avoid interference. I was going to use a 2 core cable so that I have power to both FM and DAB. Too clever for me to understand why they cant share the same power!! Quote Share this post Link to post Share on other sites
1xshaunx1 27 Posted April 9, 2020 Would they be fused independently or maybe the radio switches from one to the other with power from the radio. I too have no idea and only guessing Quote Share this post Link to post Share on other sites

Ah ok - I thought they were all powered, at least from the early 90s onwards, as both my Mk2 and VR have them. it could also be that the original area was removed when an after-market stereo was fitted and replaced with an un-amplified one - the small pre-amps fitted on the head unit side are not standard for VWs and tend to come from Halfords or a motor factors. One of the reasons for this is that reception will often be pants if you fit an after-market unit with the original area and leave it unpowered.

There isn't a power wire up by the aerial !! Interestingly whilst wasting an hour of my life searching for cables and connectors, the AM/FM connector of the aerial fits directly onto the existing cable. It will just need some tape to ensure it stays secure Quote Share this post Link to post Share on other sites

Do you use that blue wire at the back of the radio that never seems to get used? I think I remember reading that the blue wire was for speed/volume auto adjustment. Not sure it was ever used in UK or even European cars, but can't say for sure it was used in the US market either... May have been a radio dependant option.

fendervg 33 Posted April 12, 2020 (edited) The blue/white (might be grey) wire is for GALA (speed dependent volume control) -- it is splices into the spoiler control module feed and comes from the gearbox speed sensor. If it's left bare and earths accidentally it can cause problems with the spoiler. The VW Gamma 4 and a few others had this functionality, it's actually very hande - to set, pull out the tone knob to second position and to off, then set the volume at standstill to what you want, then drive at a steady 60 and adjust until the volume is right - after that it adjusts automagically! The aerial amp wire is solid blue. Edited April 12, 2020 by fendervg Quote Share this post Link to post Share on other sites
TimA 11 Posted May 30, 2020 Hi Cressa, did you get any further with this, or are you waiting for the respray to be done before finishing the job? Or am I confusing cars?! I am keen to do the same thing soon, ideally at the same time as a sunroof replacement when the lining will be down anyway. I’m a born again owner now- they didn’t have these challenges in the nineties! (Tbh, most of the issues I face now weren’t a problem back then 🙂) Any help/hints appreciated... Cheers, Tim Quote Share this post Link to post Share on other sites

Cheers, Tim Born again owner, love it. I got the car back earlier I the week so this project isn't finished yet as I work my way through fitting everything. I did run a dab wire alongside the original in the clips up to the aerial. It is on my list to do..... I have bought some 2 core cable and will connect these at the aerial base before the roof lining is fitted. I can then check the FM is working, but with not having a DAB head unit that's as far as it goes. I will connect the FM powered base side at the head unit and probably protect the dab wire there, incase the voltage where to come back down That's all my thoughts on it for now. If anyone can suggest anything else then feel free. I will put a picture up of the dab wire so far. Good uck with the sunroof swap. A mk3 golf motor and cleaning/lubricating the area are a great upgrade for them Quote Share this post Link to post Share on other sites
