3597LM with GtM60



What's the difference between the 3597lmthd vs the 3597lm? If I connect a gtm60 to the lm version, will it become a lmthd?




The 3597lmthd comes with lifetime map updates (LM) and lifetime HD traffic (LTHD). The 3597lm only has the lifetime map updates. AFAIK that is the only difference between these 2 units.

I suspect your GTM60 will work with the 3597lm but you may need to purchase a traffic subscription for it to receive traffic information.

Nuvi 350, 760, 1695LM, 3790LMT, 2460LMT, 3597LMTHD, DriveLuxe 50LMTHD, DriveSmart 61, Garmin Backup Camera 40 and TomTom XXL540s.



I have a Drive 52LM and I used GTM-36 Traffic cable and it receives traffic, not the best of the traffic options, but it works in the big city areas. I did not have to purchase a traffic subscription.

I never get lost, but I do explore new territory every now and then.
