Am I going mad, or is every cheap mount I look at designed for the XL and larger models? I have one of the original square ones, before they brought out the wide screen version. Lord knows where the original mount ended up, but I ripped the suction cup off and filed down the ball on the end so it stuck firmly in my headstock. I had imagined that buying a replacement would be simple…
This one any good
“NOT Compatible with: TomTom ONE V1 (Original Version), TomTom ONE 130 & TomTom XL (All XL versions)”
It says to visit their shop for mounts for these models, which I did, and they still don’t have a mount for a tom tom v1 original listed. I’m beginning to think its a conspiracy…
That’s for the TomTom v2 v3 which isn’t an XL one …
Same as mine, the unit is 95mm wide x 80mm high and the flutes on the back which it slides on are 55mm/60mm depending whether you measure to the inside or outside edges
I just searched TomTom mount Rider V1 on ebay and 5 came up:w00t:
Its not a rider Mo, its one of the original car mounted models.
Same dimensions as mine …
Take your pick, order a cheap as chips ‘Tom Tom One v2 v3’ mount off eBay it’ll fit 
Brilliant, thanks Art
