That's pretty cool. Look out for squeak codes 7500, 7600 and 770.

Are they the emergency ones?

7500 is hijacking, 7600 is radio failure and 7700 is emergency.

Tempting. I rarely bother plugging my phone into my car stereo. I might be more likely to use it with a Bluetooth connection. If my new car has an aux input. Will have to check that first.

What's the quality like? Battery powered?

I found the sound quality to be fine, but I think that's down to my amp/speakers rather than the adapter.

The one I have is powered over USB, so standard USB 5V charger is fine. There's probably battery ones too.

This is the one I have - http://www.ebay.co.uk/itm/221667704620 - but I wouldn't recommend it purely because of the awful announcement when you connect.

What about the GPIO - could that not be made use of rather than disabling regular USB?

Thanks. I'll have a look at them. The connection announcement does sound annoying.

My Mondeo failed its MOT last week. Bought my dad's S60 for £1. Got a nice sound system in it but no idea if it has an aux input.

I have a similar one, got it for streaming to my amp at home.

Major issues :
The annoying voice
Lack of isolation on the charging circuit meaning you can't use it while charging due to the noise.
It's so bloody small I've lost it.

If Feds call you and say something bad on me, it may prove what I said are truth, they are afraid of it.

Just looked at that ebay listing, and the images in the description.

I like this bit on a close up of the instructions:

"After matching success, the indicator light turn to twinkle slowly".

Ah yeah, there's definitely a bit of an isolation problem, but I thought it was more to do with poor isolation from my mini-amp. I think it's usually a ground-loop problem.

I had big problems with ground-loop issues with a Raspberry Pi and cheapo amps. All the USB activity could be "heard".

How do I make something run when the Pi boots up? I tried it before, I think I installed sommat which modified sommat else but it caused problems when rebooting, got stuck and I think it tried running the program again instead of closing it.

You need an init.d script, a line in rc.local or you can use an @reboot line in crontab

I'm pretty sure that's what the program I installed edited for me. It showed a list of programs, I selected mine, and it did something to make it run at startup. I'll try it manually and see if it works properly.

This plane tracking does get a bit addictive.

Just been watching a flight that was diverted from Leeds to Manchester because of high winds, then couldn't land at Manchester because of an issue there and has just been circling near my house, and I can see it going round outside.

I have the flight radar 24 pro app on my phone, tracy's frequently giving me strange looks when I'm glued to it.

AWESOME!!! No, really!

Reckon I could overload it given where I live (SE London)?

With an outdoor antenna it might overload an RPi1 but should be fine with the RPi2. I'm running on an RPi1 at the moment.

I've been making antennas and this is my current antenna

   

Popped it outside through the Velux window for a while and it was getting 4x more data.

Tonight I will be attempting to mount it outside. Then maybe fit an amplifier. It really is addictive.

 B-) I want one now...
Would you kindly point me towards one of these newfangled Internet page things describing how I should build the antenna? Thank you!
