Here's a nice little idea from Sony to give its in-car navigators a bit of added appeal.
Upcoming devices as well as current models with upgraded maps will be able to offer information on petrol prices of local garages.
With fuel costs at an all-time high you can save quite a bit by filling up your tank at garages that charge a few pence less per litre, so getting this sort of information on the move, particularly if you travel a lot, could mount up to noticeable savings over the course of the year.
It's unclear how well integrated this is at present, but much like many new tweaks and gimmicks on satnav devices, it's rare to see one company produce something unique without the others following suit.
If you didn't know already you can already check the prices of garages in your area from your computer using the PetrolPrices.com website, so if you're keen to avoid paying over the odds you can try this out from the link below.
