I got 2 slightly different mounts with mine

there are two bike mounts included which i was happy about as i also have road and mtb bikes. no hassle to change the unit from one to the other

It only comes with one mount - although it's super easy to switch the mount from one bike to the next (the mount is held in place by a rubber 'o' ring). The only issue is that you won't be able to readlily move the cadence sensor (as this is held in place with zip ties).

Two with the kit I purchased

Simple answer, Yes. I mount it on the stem of one of my bikes. Different bands depending on the size of stem. This is probably the best position actually as glare doesn't seem to be such a problem

Yes, easy stem mounting, I would say though on my road bike it needs the supplied 3m sticky pad to avoid rattling in its mount. That does the trick but you're going to get a lot more vibration riding cyclocross - obviously!

I have just received my Rider 50. Before purchasing the item, Wiggle Dean confirmed for me that the Rider 50 is now supplied with the same style mount as the Rider 35 (originally it was supplied with a different mount). This mount comes with a couple of different sizes of O-Rings and 2 different heights of rubber padding for underneath the mount. It can indeed be mounted on either handlebars or stem and fits on my fairly chunky, round profile, road bike stem.

I went to Bryton and this is what they said "Hi Sir,
If you purchase the device in England, the device will not cover Australia map and you will have to buy Australia map separately.
We strongly recommend users to purchase the device locally to receive the service and warranty locally. Products purchased from overseas may have to request for overseas distributor for service and warranty.
The additional map can only be purchased from our e-shop (http://www.brytonsport.com/eshop).

Best Regards,

Hi AusRama, the bryton comes with a map set for the region that it was shipped to. So if you order it in the UK you will get the Europe map set. The versions for NA or Asia will come with their own map set. If you happen to get one without the correct map set, the ryder used the openmap project for its maps and you can download and install those with the provided software.

Included is a dvd and SD card that contains navteq maps for UK and Europe, from these you can activate ONE map, any additional maps must be purchased through bryton

(HD maps start at 69 euro and are not available for digital distribution, shop or mail only)

OSM were used on a previous version of this device but since the deal with navteq this is no longer the case

Currently the units are shipping with Navteq HD maps and in the UK they cover Western Europe (excluding Nordic) and you can enable one for free. You get an SD card and DVD of the maps.

no, older versions of this unit used open street maps but since the last update the only maps that can be loaded are those purchased through bryton

I'm pretty sure you cant, and even if you could, I dont think the screen resolution would be nearly good enough. I'd suggest a Satmap Active 10 or Garmin 800, expensive I know.

Yes it will guide you home. You set 'Home' as a point of interest, and then select it as your destination. One line appears on the map of the direct line to the destination, whilst a route is also shown on roads. It doesn't appear to identify bridleways though...

as far as im aware you cant plot a route on the divice while out, but you can set a destination and it will navigate you there, or navigate to places of interest. hope this helps

I purchased one in May 2012 and it works fine with my MacBook

Yes

I use the garmin GSC 10 sensor with the Bryton 50. That way you only need to buy one sensor. I believe the Bryton sensor only works as a speed or cadence sensor

OSM maps are no longer usable on this device, you have to use navteq and you have to pay 69 euro per region, really bumps up the price of what on the surface appears to be a budget friendly option

from what i can tell the rubber goes on the bottom front of the unit to stop it rattling on the bar clamps if you have mounted it onto your stem
the cable tie can be used to secure the mount even more if you are mounting to your bars
