I worked on installing Emma in my Mini this weekend, replacing a Blaupunkt tape/radio in a sled.

I noticed that the empeg sled dimensions are slightly different to the Blaupunkt; if you can imagine the sled aperture, then the width is exactly the same but the height is some 1.5 mm smaller. This meant that the dashboard aperture was too large, and the sled just wouldn't locate cleanly - it slipped back throught the dash when the unit was inserted as the tiny flange around the sled aperture just didn't engage with the dash to grip it properly.

I had a look at a couple of dashboard sleds I have, for comparison. I have a Philips "generic" conversion sled, a Philips RC629, a Grundig, the Blaupunkt, and a Sony. The two Philips, the Grundig and the Blaupunkt have *exactly* the same external aperture dimensions, and the Sony is the same width, but 0.5 mm taller. The empeg sled is definitely the odd one out in this bunch, as it is shallower. Has anyone else experienced this?

I ended up binding the empeg sled with tape to increase the external dimensions so it would fit the dash aperture, but while this made it a better fit, it had the effect of effectively reducing the flange's depth, and therefore it's ability to "grip" the dashboard properly. A less than satisfactory installation, I'm afraid. Ideally, the sled dimensions should be changed slightly if my less than scientific survey is anything to go by; unforch, I don't have access to the DIN standard definitions for car devices, so I can't argue this point with any weight. If the aperture height was increased by 1.5 millimetres, this would also require the "bumps" that locate and grip the head unit when inserted to be punched in deeper by 0.75mm.

A couple of other small gripes; when inserted in the sled, the facia of the empeg doesn't cover the sled flange, leaving the top and bottom edges of the flange visible (the sides of the sled are nicely covered). Ideally, the empeg faceplate could do with being extended slightly in depth, by about 3mm.

Finally, the handle; it is machined with square section. At the point where it pivots on the unit, the square section cuts into the facia when it is opened, which is at that point *radiused*, rather than square. A small niggle; either the handle section at this point should be radiused to match the profile of the facia panel's cut, or the panel should be square cut to a more generous dimension to clear the handle when open.
