Here is a great mount for the Garmin Nuvi. Excellent value on a heavy duty handlebar mount that fits handlebars up to 1 inches. We even include rubber strips so that this mount can be used for much smaller handlebars.

This can be easily removed. This uses the cradle that came with your GPS.

Fits all Nuvi and many StreetPilot models including:

Garmin Aera: 500, 510, 550, 560
Garmin Nuvi: 30, 40, 40LM, 50, 50LM, 200, 200W, 205, 205W, 250, 250W, 255, 255W, 260, 260W, 265T, 265WT, 275T, 370, 360, 350, 310, 300, 465T, 500, 550, 680, 670, 660, 650, 610, 600, 785T, 775T, 770, 765T, 760, 755T, 750, 885T, 880, 860, 855, 850, 1100, 1100LM, 1200, 1250, 1260T, 1300, 1350, 1350T, 1370T, 1390T, 1450, 1450LM, 1490T, 1690, 2200, 2250, 2250LT, 2300, 2300LM, 2350, 2350LMT, 2360LMT, 2370LT, 2450, 2450LM, 2450LMT, 2455LM, 2455LMT, 2460LM, 2460LMT, 2475LT, 2495LMT, 2555LT, 2555LMT, 2595LMT, 3450, 3450LM, 3450LMT, 3490LMT, 3590LMT, 3550LM, 3750, 3760T, 3790T
