Google Maps on Android downloads 60MB in 10 minutes

I was just having a look at my Vodafone account to see how I’ve managed to use 2GB of data this month (oops), and noticed these series of entries:

...etc

That’s about 60M in the space of 10 minutes. Which seems like a lot. Similar patterns appear at regular intervals..

Looking at the times of the entries, the data usage is due to Google Maps running on my HTC Hero, which I’m using for sat nav.

If that happens on, say, 10 days in the month, then that’s already 600M of data used. Hm.  (Add to that the Spotify usage, and 2GB starts to make sense..)

Anyone know if Google Maps can cache its data on Android?

Resetting the oil service light on a 2006 BMW 320i

The oil service warning light on the BMW was still on after the last oil service, so I looked around for how to reset it. Lots of advice on the internet, but mainly involving special tools (aka paperclips) and dodgy shorting-out of pins in the diagnostic port.

There’s also talk of holding down the trip reset button whilst turning the ignition key to the first position, then releasing and pressing and holding the button again. But there IS no ignition key in the recent BMWs..

The answer turned out to be a bit more easily guessed (after a bit of trial and error). When you start the engine, the oil service warning shows on the dashboard, at which point you just press the BC button on the end of the indicator stalk (which is how you access most of the diagnostics anyway). The word “reset” appears, and another click and hold on the BC button makes it show “resetting” (and a little clock icon so you know it’s busy). And that’s it.

Put away the paperclip.
