This is the one I'm going for with my Sony Xperia Z Ultra

Cheers, just on it now

Hi guys, thought I'd bring this back up instead of starting a new thread:
an old chestnut I know, but any thoughts/ ideas on sat navs, cos the iPad in my tank bag is ok for getting from A to B but not ideal for proper routes or twisties plus my 12v socket can't keep it powered for more than 4 hours ...
