I have posted several times about the ability to listen to AM in the car. Maybe this one will stick. I'll explain how I accomplish the task, but I'm sure it can be done many other ways.
First, you should have a wireless plan with unlimited data. Common in USA, but perhaps not everyplace else.
Next, being a patron is handy as the 128K stream is essential to listen to AM on an above average car stereo system.
Your car should have provision to accept a 3.5mm AUX input. You can connect your mobile phone via FM or cassette too, but I had spotty performance with these in the past. AUX input much more common in newer cars since 2006.
The rest of this is specific to my rig. I've been using this for over a year.
Carrier = AT&T (3G service is almost 100% coverage in my local area). $30/mo data plan is mandatory.
Device = iPhone 3G. In the USA, we can get an 8GB 3GS version for $99
Application = Wunderradio costs $7 (allows entering custom stream info), or if you don't want to spend the money, FStream is a free app that will work as well.
Connection = el cheapo 3.5mm male patch cable. $5 at Radio Shack or your favorite electronics store.
Power source = Belkin micro $20
(this is very important because streaming internet radio draws more current than conventional car chargers. You need something that can supply 1A or greater.) If you don't do this, you'll eventually run the battery down in the phone.
Placement = Apple dock $29 for my iPhone to make it easy to sit the phone and control it. The dock sits in the center console behind the stick shift. (yes, some americanos like to shift for themselves.
)
Et voila', you can now enjoy AuralMoon almost everywhere.
