I usually use my phone for directions, but lately it seems that using the phone's GPS system significantly drains the battery AND my data allowance. Finally decided to buy another Garmin (had one years ago) as I figured it would pay for itself and be a better deal than increasing my data allowance.

The manufacture made good with a replacement. But there are quirks. Sometimes routes supplied are plain stupid. More than once the voice literately says TURN RIGHT when the visual clearly showed LEFT. The visual is more accurate.

Purchased this Garmin sat-nav in July and it is perfect! Took a while to get used to it, but we travelled from Chester,toured down to Devon and Cornwall, then to Dorset. Very clear instructions and good sized screen. Recommended. The extra information on screen was very helpful.
