I recently bought a used nuvi 3760 on ebay. It came without a TMC cable. I thought this was no problem as I still had a GTM25 cable from my old nuvi.
Unfortunately my old cable has a mini USB connection and the 3760 has a micro usb socket. It doesn't fit!

Now I am searching on the web which GTM cable has a micro USB connection but I can't seem to find one. The Garmin website states a GTM35 is compatible with the nuvi 3760 but the picture next to it shows a mini USB connector that won't fit.

Help!

Any info much appreciated, especially if anyone knows any third party (cheaper!) TMC cables that will work as the original Garmin ones are priced pretty steep.
