If the cable is faulty then it is best for you to contact the Garmin customer services team directly on 0808 238 00 00 as if a payment is needed it is cheaper to get this replaced than to purchase a new one, otherwise the part that you require is the gtm 25 which can be found at
https://buy.garmin.com/shop/shop.do... (although this is currently out of stock) and has a rrp of £49.99 it can also be found by performing an internet search on the part number which is 010-00722-01
