Re: [tracker2] Nuvi 1490 FMI?
- So, I could use either
https://buy.garmin.com/shop/shop.do?pID=104982 (if I wanted traffic)
in conjunction with a RS-232 level converter and 5v supply? Seems
pricey, but if that's what it takes to keep my nice trim-line T2-135
installation and preserve messaging, I'll do what I have to do. I just
want to make sure it'll work before plopping down the $$$.
Or do those cables include a level converter as the 10813
(https://buy.garmin.com/shop/shop.do?pID=1449) seems to? Or does Argent
add the "inline converter circuit"?

PS. Or assuming https://buy.garmin.com/shop/shop.do?pID=1449 is the
cable inside the Nuvi350->T2-135
is it actually your own
can I carefully open something up and replace it with a new cable based
on either one from the links above or your 5 conductor pigtail?
