TomTom 1.9 on iPhone 4S "Accessory not Supported"

Nov 10, 2011
Hi Folks,

I have TomTom Western Europe 1.9 on my iPhone 4s. The app works great but when I plugin an official Apple datacable to a car cigarette lighter USB converter (belkin) I get a message saying "accessory not supported"?!

This is rediculous as it's just a charger?!

Does anyone know why? Can I fix it? :mad:

As long as you are not using a dock mount, there are charging adapters that you can connect between the iPod connecter and the iPhone. I would suggest that you first try a different USB Cigarette plug adapter, I use one that I picked up a truck stop for $3.00.

Otherwise you can try one of these: (please note that *I* am not selling these items)
