...are people here using the Automobile GPS instead of the zumo with any success?
Hi Ken:
Way back in the 'old days', when all Garmin automotive GPS units were waterproof, long before Garmin ever thought of making a motorcycle-specific GPS, I used the StreetPilot 3, and various 2600, 2700, and 2800 series automotive GPS units. They worked just fine for motorcycling. What was significant back then was that Garmin either offered motorcycle-specific mounts for these devices, or, the all-purpose mount that came with it grabbed the device sufficiently well that one didn't have to worry about the unit bouncing off the bike if you hit a pothole or big bump.
The current series of Garmin motorcycle-specific GPS units offer a few additional 'features' aimed directly at the motorcycle community, such as twisty road routing, fuel tank reminders, resistance to gasoline, etc., but I honestly don't think that any of these 'features' offer sufficient benefit to offset the very high price differential between the Zumo series (motorcycle-specific) and the mainstream Nuvi units. I am a little bit vexed at Garmin as a result of the very high price differential between the Zumo series and the Nuvi series.
I'm sure that a Nuvi would serve the purpose perfectly well for motorcycle navigation, but there are a few things you should probably investigate very carefully before making the purchase:
1) Security of the device in the mount - does the mount hold the device securely? If not, could it be easily modified
by you to hold the device securely in the mount?
2) Attachment of the mount to the moto - in the old days, all the automotive mounts had 4 little holes in the back that lined up perfectly with Ram-Mount brackets. Check to see if the mount that comes with the device can be easily attached to a Ram-Mount.
3) Will the touch-screen respond to being pressed with a gloved finger?
4) Can you easily protect it from water by just encasing it in a Zip-Loc bag? Or, better even still, can you live without it (by keeping the device in your pocket) if it is raining out?
5) Can you live without the voice guidance (because I don't think that the Nuvi devices are designed to transmit audio via Bluetooth)? FWIW, I didn't have any voice guidance at all for the first 8 years I used GPS on a bike, that didn't cause me any problems.
6) Is the device capable of downloading, storing, and navigating a route you create in BaseCamp?
I think that if the answers to the above questions are satisfactory to you, then you should be pretty happy using an automotive device (a Nuvi) on your bike.
