I have owned Garmin GPS's since their first aviation unit, and had many other of their subsequent aviation units, as well as automotive, hand-held, and motorcycle units. I have owned other units as well from other manufacturers. One thing is clear- upgrades are expensive, and like everything else, the excitement lasts only until the next model release. In Garmin's case for motorcycle use, the excitement has lasted much shorter a time than with their other products. They have proven buggy and problematic, but still remain expensive. This has led me to go another route entirely; trying to have the same functionality while saving hundreds of dollars on yet another stand-alone Garmin unit. I have been waiting to replace an aging iPhone 4 with another phone, but needed it to be water resistant to handle motorcycle use. Enter the Samsung S4 Active. This is my experience with that phone so far in the quest to kick the Garmin habit. I've had a Samsung G4 Active (water-resistant) phone on my 2011 GS for one month, and it works very well for my needs. It cost a mere $150, is water-resistant enough for any rain storm, has a large screen to compete with a Garmin display, Bluetooth connectivity for my helmet Bluetooth system for communication, and ample storage capability. Touch screen sensitivity seems useable, even with gloves, even though a "glove" mode exists that I have yet to try. Screen brightness is useable when set to "auto" even with a smoke shield. In the brightest Florida sun, it does wash out slightly, but setting it to full brightness is not worth the effort or power use. The S4 is mounted on the optional bar mount, where formerly, a NAV IV mount from the previous owner was located. I removed the NAV IV mount and replaced that with a RAM X-Mount/bar mount combination. The X-Mount IS solid, and easy to mount/dismount the phone, but by virtue of design, has the ABILITY to slightly rotate off-center. However, on-road bumps have not yet forced rotation. I am using the "Co-Pilot Live Premium- USA" app ($9.99) for navigation. This allows downloading of maps and "offline" navigation which doesn't eat data time. The US map requires 1.2 GB. I opted for downloading regions instead. My understanding is that updates are quarterly. The program is feature-rich enough for routing, re-routing, waypoint storage and trip planning for my needs. Occasionally, the app, if left running, and the phone is switched to another app, then back to Co-Pilot, is buggy enough to not respond and must be forced to close, then re-opened. In use on the bike, this is of some concern, but has not yet proven to be an actual problem. Also of note, "offline" mode is not the default- one must disable data network usage within the app. I am using the 2 amp BurnsMoto USB connector for power/charging. While using the GPS, the Samsung S4 will still lose about 1.5% of charge per hour. I was warned of this, but dismissed it as inaccurate information because I knew the AC charger supplied with the phone was 2 amps. I have yet to measure the current while in use, but even with 1.5% an hour, leaves plenty of time for statewide use. Closing Co-Pilot which turns off the GPS, the phone shows a positive charge. As I don't use the GPS 100% of the time, even on IronButts, this isn't a crisis. So now I have kicked the Garmin habit fo motorcycles. I found an entirely capable, cheaper replacement that works with minor caveats. Goodbye Garmin.
