So, I've been running GPS units on my bikes for over a decade now. And we all know that smart phones don't work without cell service and we all know that the best places to ride don't have cell service... so a dedicated GPS unit that cost at least $500 USD is the only solution. So, what do we really get for our $500+ bucks? Here the features listed for a Zumo 595 with a MSRP of $800 and mu comments ... Display resolution, WxH: 800 x 480 pixels - Phone has much higher resolution Transflective display - Whatever that means Rechargeable lithium-ion battery - Phone has a rechargeable battery too Battery life up to 4 hours - Phone last about the same with GPS running and the screen lit IPX7 waterproof rating - Current Phones are also IPX7 and if not you can get a case. High-sensitivity receiver - whatever that means. Headphone jack/audio line-out- Phone too Maps & Memory - Okay, traditionally at the end of the day, this has been the winner for GPS, but now apps let you download and save maps on your phone Preloaded street maps - see above, and for daily Navigation, a Smartphone is smarter Includes lifetime map updates - Phone have continuous map updates. nüMaps Guarantee - whatever, Google maps have never let me down. Built-in internal solid state memory - Phone too... is this really a "Feature" Accepts microSD data cards (not included) - (Some) phone too. Custom POIs (ability to add additional points of interest)- Phone too Ability to save 1000 waypoints/favorites/locations - that's all? Speaks street names (e.g. "Turn right ON ELM STREET in 500 ft.")- Phone too Lane assist (guides to proper lane for navigation)- Phone too Junction view (displays junction signs) - Ever heard of Ways? Route avoidance (avoid highways, tolls etc.) -Phone too Bluetooth wireless technology- Phone too Speed limit indicator (displays speed limit for most major roads in the U.S. and Europe) - Ways tells me were the cops are! (With a data connection) View upcoming points of interest along route - my phone does that MP3 player- I've never used this... never. Trip Planner - Trip Log Tire pressure monitor system will support up to 4 tires (individual sensors sold separately) Dual orientation display Garmin Adventurous Routing Streaming Spotify & Pandora music/media players Smart notifications - My Garmin has been bitching about "Small Craft Advisory" for like a year. LiveTrack - Phone, and Spot Compatible with Smartphone Link - My phone is a Smartphone Live traffic and live weather via Smartphone Link app - Why not just use the Smartphone? Rider alerts - There's an app for that Helmet Law notifications - ATGATT 3D Terrain - Phone too Round Trip - Phone too Service History Log - App for that. VIRB Control - App for that Track Support - I don't know what this is. Custom Map Support - Phone too TOPO Map Support - Phone too Pandora Support (with compatible phone) - Why not just use the phone. Removable Battery - Some phones, but so... I do use my current GPS unit to control my phone, answer calls, and I build routes in Basecamp But this year I've been using Rever more than I've been building routes. And Ways is just easier for daily navigation from Point A to Point B. And new bikes are starting to integrate Phone Pairing into the handlebar controls. As I'm looking at the 2018 KTM R1290 SAR, and trying to decide the best way to mount my GPS and phone... I've started to realize that the GPS on my bike is almost as useless as the one in my Pick-up. Thoughts? Am I missing something?
