Used to have viewranger installed on my mobile, this proved to be reasonably acceptable for me. Then earlier last year I subscribed to OS package for £20ish and I'm pleased I did, far far better than VRanger, and at that sort of price it falls nicely into (Christmas/Birthday presents), daughters and wife never know what to get me. Glad I spotted this thread, never knew I could use Tesco vouchers, £8 makes it a done deal for the next 12 months at least
