The TomTom app lets you navigate 50 miles a month for free. However, if you want unlimited miles it normally costs £15 for 12 months. I just noticed the price have dropped 50% for 12 months to £7.49. I paid for 1 year, waited till the payment went through, then paid for a second 12 months unlimited & it's gone through. So I now have 2 years unlimited for the normal price of 1 year. I know many users here don't like any navigation app that costs money, but I posting this for those who already use TomTom but want unlimited miles. The Google app looks exactly like the TomTom sat nav units. I don't know for certain, but I believe it's running exactly the same software. I don't expect this to get much heat, I'm only posting to help anyone who might be interested in the offer.
