How to install a Sony CDX-DAB700U car radio in a Vauxhall Corsa D Introduction. This comes with or without an internal windscreen-mounted DAB aerial. I chose the option that came with; it is possible to connect the radio to your regular aerial, but this is a. I am considering installing an external whip antenna. I see you can get combination FM and DAB antennae.

If I forget thee, do not thou forget me.
I know in a Z3 the difference isn't great, but the higher you aerial the better. DAB transmissions in the UK I recall are cross polarised for the main transmitters. Having the antenna either vertically or horizontally wouldn't make much difference if you're pointing at the transmitter, but, there is a but. In terms of positioning, having the aerial vertically in theory should provide better more consistent reception in a car. You antenna will always have a decent vertical and/or hoiztontal component irrespective which way you car is pointing.

If you put it horizontally, when you are at 90degrees to the transmitter you're presenting very little of the antenna to receive a signal. As DAB is very sensitive to receive levels, I would have thought that a vertically placed aerial is much better than an hoiztontal one with less chance of loosing signal. The way DAB works is there is a great deal of error detection and correction built into the transmissions. This effectively have a signal or you don't. You don't get fading as you do on FM and AM. I suspect you will get far more dropouts on DAB, especially if you listen to stations on local DAB multiplexes with a horizontal aerial.
BBC National services and others like Planet Rock and TalkSport on Digital One you should expect slightly better service due to the higher transmission powers and greater interlocking of transmitter areas. Something else to note is that many stations that broadcast in stereo on FM only broadcast in mono on DAB.

Counter intuitive I know but it's true. I suspect as some stations abandon FM in coming years it will free costs to pay for them to pay higher DAB transmission rates for Stereo. Where do you live and usually listen to your car radio?
I'll take a look at which DAB services are available and if they are stereo there when I get back into work next week. I know in a Z3 the difference isn't great, but the higher you aerial the better.

Looking at DAB and then mobile internet (provided by mobile phone service providers) the possibilities become mind boggling. The issue with mobile internet services is that someone has to pay the data costs.
My wife's E89 has it installed (and paid for life in the car purchase) but in reality, it doesn't get used much. The best bit is to download satnav details from your phone before you leave home. However, the manufacturers (and dealers) typically get more from it than the car owner. They get all the diagnostics and usage information. They learn what's going on in near real time. They could call you about a problem long before you know it yourself.
Am sure more innovative ways will be found to use mobile internet and data. Cars will automatically connect to emergency services via apps in case of an accident etc. DAB has a much greater data capacity than the data carrier in FM signals (RDS etc) but less than mobile internet. I'm sure that manufacturers could find ways of doing over the air downloads via that rather than mobile data as it would cost less, but, is a one way service. Of course, dealers wouldn't like that though because it means you don't have to visit them and pay exorbitant rates. Coverage of both mobile data and DAB are an issue. Mobile phone companies only provide service where there are revenue paying customers to use it.
DAB is the same - it's paid for either the BBC or advertisers on commercial stations. You'll probably only ever get 95-97% population coverage which equates to 85% geographic coverage. Most people rely on the far richer data provided in mobile satnav said rather than those that use RDS based data. At the moment those kinds of service are bundled in and I think the car manufacturers will realise they are missing a potential revenue stream by giving it all for free as soon as they put mobile internet in your car.
At the lower ends of model ranges, I'd expect them to start providing fee paying services and bolt ons. I think you'll see far wider variety of mobile internet based services across cars. On third party radios, it's likely data services will be supported by you own mobile phone rather than its own mobile internet or that of the car. 3rd party audio is being squeezed out by integration from the car manufacturers even at the lower end of models. The worrying thing is the extent to which big brother reaches further into your life as a consequence of integrated automotive mobile internet.
Imagine the commercial benefits that provides fuel companies and other Automotive suppliers! It's completely independent of the apps you choose to put on your mobile phone and browser use!
It could work to the motorists benefit. When you get low on fuel, the fuel companies could bid for your next fill up and give you their prices on your dashboard display. All kinds of things become possible. It's there and possible now. Thankfully the car manufacturers haven't yet opened that hornets nest. This is way off DAB but interesting.
Stick with a dumb car!!! Click to expand.Not sure about that - just the ramblings of someone looking for an angle to create a few quid It's the industry I work in so is of interest to me (and probably nobody else ) The obvious question I didn't answer was would/could radio be delivered to car audio via mobile internet. Yes it could technically, but someone has to pay for that mobile data airtime. Also there's 20-30 seconds latency on the encoding, distribution and buffering of web based audio. Maybe not a big issue but that creates problems in real-time two way interactive broadcasts, phone-ins etc (not that you should be doing that while driving!). Why bother with the problems it creates if it can be done via broadcast anyway.

You're more at risk of service issues on a commercial phone network than a very closely regulated broadcast environment. Could be used as a niche solution for specific applications, but for the wider radio solution - put in a DAB radio.
Some newer car radios accept streamed services from your phone - that's your airtime/data you're eating into then.
