Thread: Garmin ecoRoute -Save Gas and Money

Ok, I'll try the mass storage feature when i get home. But I think catymag is probably right with the mass storage solution because my 3490 does shown the "orange" computer and listed as a device when USB connected to the PC and not my nuvi 50, its white and shows up as mass storage. I'll let you guys know what i find later.

Neil, I guess dasilvarsa wanted to see my 3490 supported features, so that's why i was trying to look for the hidden ".system" and the "140.bin"...But again for setting up the ecoRoute profile, I was able to do that when I first tried it. It did let me choose the "car type, gas type, city mpg, highway mpg, and fuel cost." But as soon as I finish doing that, it ask for the HD accessory unit, and I cannot get any further than that. So now, everytime I tried to open the ecoRoute app, it will keep asking me to connect the HD accessory unit in order to use it. So what I'm trying to do here is to use my ecoRoute app without having to purchase the HD accessory unit, if that's possible? I seen on some threads, there's a "standard" ecoRoute and "HD" ecoRoute, and it looks like I have the HD version. So my question is, can I use the ecoRoute without having to purchase the HD accessory unit and/or change my ecoRoute app to the "standard" version? Once again, sorry for my stupidity and thank you guys for all the help.
