I am just looking around at getting my first ever bike gps and have been looking at the above but need some help.
Most of the sites say that base map is pre loaded but there is a slot to enter more info. As it comes straight out of the box would i be able to set for instance a finish point and it would tell me like a tom tom sat nav turn left, turn right etc or do I have to buy and load other information/maps?
I've no experience of the Edge 605 but I use the Edge 800. Both models come with base map, but it as much use as tits on a bull, its what its name says "base map", probably 99% of the roads in the UK are missing along with built up areas. The only roads that are in base maps are major roads, no minor roads etc so the map is off no use in reality.
The slot is for a memory card if you buy maps preloaded onto a micro SD card, but there expensive, alternatively you can download from your PC either into the internal memory or the SD card.
The maps I use are from free mapping sites and I just download them into Garmin Mapsource, a free program and then upload to the Edge
FREE UK (GB/Ireland) Maps Home (talkytoasteruk)
Worldwide routable Garmin maps from OpenStreetMap
The Edge will give directions but not audible but will flash up on the screen when to turn etc along with an audible beep, I think, I'm half deaf so I don't hear anything.
In my opinion if you can afford it go for the Edge 705, or better still the Edge 800
If you look at the following page there is a good review of the 705, the only difference between the 605 and 705 being the 605 does not monitor heart rate and cadence, I think
