Do not go into my GPS Tomtom

Buy to connect my GPS TOMTOM on drums, both placed in a cover So Easy Rider attached to the handlebars of my bike, I needed a short extension with angled connector. Unfortunately, the angled connector is too big and does not fit into the hole of the GPS socket. I'm seen me late, I tried to tinker with the retailer, but to no avail ... A purchase for nothing.
But let's be fair: the extension works perfectly.
It is simply inappropriate for the purpose for which I had destined.
