As I've read in other reviews, the Edge 705 base map is better than the 305 but no where close to what you would expect from an all-in GPS unit. If you want to obtain map detail on your PC and you GPS unit, don't buy the micro SD card but rather purchase the DVD version. I've confirmed from Garmin that if you purchase the DVD version, map detail can be viewed on your PC and the 705. All you need to do is copy the DVD to a micro sd card which you can insert into the unit.

As some of you may have found out, the micro sd card that comes with map detail can not be loaded on your PC which means you won't see the detail from your rides once you download them to the GTC software. Hope this saves some people money as well as miminizes the frustration.

For me, a bike GPS is primarily interesting because of the possibility of navigating while riding the bike. Having speed, cadence and distance info is nice, but you can get that for a fraction of the price without the hassle of having to remember to keep your bike computer charged. Any Cat-Eye will run for at least a year on a set of batteries. This Edge 705 will need to be charged at least weekly if you are an avid rider.

I like to go out for rides in a random direction and then use the GPS to guide me home. I also like to plan rides carefully at home on the computer, download them to my navigation device and ride a route with turn by turn directions, not needing to ever consult a paper map during the ride. I don't download performance (speed, cadence,heart rate) data to my computer an analyze it. I just don't care about that data. I don't use the heart rate monitor. I used to use heart rate monitors but no longer am training seriously enough to care.

I also find that having a mapping GPS on my bike is entertaining. I get to watch the map as I ride and find out the names of parks and other large green areas around me.

The idea of having turn by turn navigation on my bike has long appealed to me. I bought a GPS 60 CS when it first came out, and then upgraded to the Garmin GPS 60CSx Handheld GPS Navigatorwhen it came out (but more sensitive GPS reception). To get navigation with that device, I had to buy the city navigator DVDs and plan my routes using Mapsource on my PC. The 60CSx only comes with base maps.

Mapsource is functional but primitive and rough around the edges from a user interface perspective.

I have used my Garmin Edge 705 for a little over a week now. I upgraded from the Edge 305. When I first received my 705, the instructions stated to charge it before using it. The 705 came with a half charge so I didn't think it would take that long to fully charge it. 2 days later it was charged. Garmin Support told me "The expected time of charge is around 3 hours. The problem you see is a software bug. Let the unit run completely down and once you charge it next time it will show the correct information." Since doing this, the charge times are back in line.

Using the 705 is very similar to the 305. It uses the same handlebar mounts, heart rate monitor and cadence sensor. The 705 is slightly larger in size and uses a `joy stick' located between the Lap and Start/Stop buttons for navigating the menus. So, those with the 305 should have no problems adjusting to the 705.

Mine came with the pre-loaded Navigator maps. Using Garmin's MapSource, you can download waypoints and routes to the 705. The 705 has an auto-routing feature to guide you from waypoint to waypoint. It has three modes to adjust your route from point to point (Car/Motorcycle, Bicycle, and Pedestrian). Using the Bicycle mode, my routes went waaay out of the way and added many unnecessary miles. Even though I told it to avoid unpaved roads, it tried to route me down several. If you miss a turn, it will re-route you back on course. It would be best to use a third party mapping software and download more precise waypoints/routes to the 705. In Car/Motorcycle mode, it looked to route fine.

The battery life is very long (about 15 hours)! I left it on overnight and woke up to it still running. My 305 had problems with turning itself off when going over bumps.

Verified Purchase
Oct 13, 2012: I have now used this 705 for two years, and here are things you need to know (but the manual does not tell you):
1) There are two digital data displays - you will discover this, no doubt, some time after beginning to use the device - and you switch between them by double pushing upward the "thumb stick" (Garmin's terminology): the first push illuminates the backlight (if you have set this in setup/display). Garmin calls these "bike computer 1" and "2".
2) Altitude is NOT derived from the satellites (a possibility, when more than 3 satellites are visible to the receiver) but rather from barometric air pressure. This means that it needs to be calibrated, as air pressure changes not only with altitude, but also with weather. You do this by setting it in the "menu/save location".
If you start commonly from one spot, say your home, you need to save this location, with the known altitude. Do this for several spots around your starting point, as a difference of about 10 feet from one starting point to another is enough for the device to not recognize the spot (this is the limit of accuracy of the GPS system - for civilian use). Then, when you start your ride and press the start/stop button, the unit will recognize your location and use the altitude you have entered. This will automatically calibrate the unit for that particular ride.
This also makes the absence of a temperature sensor all the more odd - the crystal used for pressure should be `temperature compensated', as its expansion with heating will change the altitude. ?? Why Garmin decided to dispense with this is anyone's guess.
It also explains the substantial `drift' I noticed in altitude measurements - see the original review below.
