I have already spent the change from $1000 many times over last week
A CB is already on the bike, but I did buy a $20 80 channel one from Jaycar for offbike use and testing, as my more expensive handheld gave up the ghost
I think a unit like the 660 that is easy to put on the bike and take off means I will use it a lot more, as no more fiddling with cables all the time. Thats why I went for a bike mounted CB as setting up a hand held all the time meant I did not use it much.
I have been playing around with all the features on the 660, and seems to exceed my requirements. Integrates with my mobile and all the phone book features work. Routing as with most GPS devices has ups and downs, but it will get you there in unfamiliar places. As Des said, the ability to store various customised routes is great, as is route preview which means you can see how the route works in practice. I have been able to plan routes easily on the unit, but have to learn how to use the computer planning software sometime.
Once the cable to interface with the GPS arrives I will give it some bike time. The way the GPS switches between car and bike use just by the cradle it is in is a neat feature. Emily sounds rather hot too, but I won't try and look up the real person just in case
