Two Problems With Garmin 605 - Help

I wrote Garmin because my 605 handlebar mount was loose and I wanted to see if they had another since mine was apparently defective. Their response was "Thank you for contacting Garmin International.Garmin only has one bike mount available for the Edge 605. You can order one from the Garmin website, the mount has been redesigned and appears the same as the older mounts, however it should not break or be loose." I wanted to say 'duh' you should have improved it since it is so flimsy and poorly designed and produced. Now the clip that holds the GPS in place is broken and it will not lock. They have a redesigned mount that should not break or be loose but it costs $13.50. That's a lot of money for a cheap piece of plastic made in Asia. Is there a way I can wedge the GPS into the mount or some other fix? I am going to get one of those squeeze lemon things and superglue it on the Garmin somewhere so when people ask - I can tell them the Garmin mount is a true piece of junk.
Second issue deals with accuracy. All of the mileages on my rides with the Garmin have all been recorded within a +/- of .01 miles. Recently, the 605 is over from .23 -.51 miles on a previously recorded 30.1 mile ride and .43 miles over on a 34.6 mile ride. Why the change in recording accuracy?

Here it is for $12 and free shipping.

One possibility for the distance discrepancy is if you are riding twisty routes with poor GPS reception such as under heavy foliage or between tall buildings. Under these conditions, the gps will show shorter mileage than actual. This is one reason Garmin includes a wheel sensor with the 500 and 705 .

I need to put this to rest. Thanks for the 22 people who viewed and the one response.

On the first issue with the mount - the only part I need is the piece with the clip as shown in the lower left quadrant above the zip ties. I cannot see paying $12.00 or so to get that 20 cent piece of plastic that is prone to breaking. I'll superglue the GPS to the broken mount before I will pay that much. Then all I will have to do is cut the five cent zip ties when I need to rewrap the bars and I will be able to download and charge with the GPS still on the bike. It's the principle of the thing and furthermore, I am just a poor pensioner.
For the distance, thanks for the thought. The routes that I described are rural with no overhead canopy and no buildings of any sort. I guess it is just another example of a piece of junk like the elevation readings that I get. I was in Florida recently riding along the coast and the elevation varied from 62 feet ASL to -22 feet ASL. So much for that worthless function. Yeah, I know it's not barometric so it is prone to be worthless. In all kindness I am - Don

GPS elevation is generally less accurate than position due to geometric realities of satellite orbits. Barometric sensing of elevation is problematic due to the extremely small change in pressure with elevation changes. A change in elevation of 100 feet only changes barometric pressure by ~0.035%. Changes in atmospheric pressure due to weather systems can be much greater than this.

I use an Edge 705, and find it's position, distance, and altitude recording sufficient for my purposes. It has a lot of bugs navigating gpx tracks, which is what I consider its major failing in my use.
