Hi, how far exactly are the holes from each other?

Hi, sizes are 40mm and 30mm,apart ! there is two way,s the hold? could be fitted,plus you could drill your own holes, hope this helpsRegardsEric Donaldson

Would it fit a Tomtom Start 20 please?

The product description already notes the compatible devices - including two different TomToms - copy / pasted below. Garmin zumo 400 Garmin zumo 450 Garmin zumo 500 Garmin zumo 550 Garmin zumo 660 TomTom Rider 2 TomTom Urban Rider

Does this item come with any bolts/screws to attach it? If not does anyone know the diameter of the holes?

Nothing supplied, but I was fitting it to a Triumph nav mount. I went to a shop and got stainless steel bolts, washers and SS nyloc nuts. I can't remember the size, but I think it was 5mm but they were a tight fit and had to be screwed in
