My wife got a zumo 590LM with her '15 STL. I have a 3yrold 660LM installed on my '15 RT-S. It's always been quirky but got the job done.
Having both devices I have found the 660 is yesterday's technology BIG TIME by comparison. When we both are riding the same basecamp-generated routes, both gps's take us different directions, esp. in urban areas (same maps, s/w updates & prefs). :banghead: She gets much clearer directions. Also when we are slow or stopped at a complex intersection, her 590 updates her direction & route instantly when mine slowly shows I'm pointed in a different direction altogether.
I'm considering an upgrade for my RT and weighing my options. I figure I can resell the 660LM, and spring for the 590, but the spyder mounts/harnesses are different.
Any ideas on how to change the mount (I have std. bars) and wiring without coughing up another $250 for a 590 OEM harness/mount? The cost of the 590 is bad enuf. :yikes:.
(BTW, Have actually seen the price of the 590 drop since the 595 came out).
I'm thinking, gotta be the same wires to the bike coming off of both setups. But I don't know what's involved in the switch to do it myself.
