Hi,
I have been looking around for good deals on GPS and found the following two models.
First of, LMT stands for Lifetime Map & Traffic updates, whereas LM is only Lifetime Map updates.
Also, by Lifetime they mean the lifetime of the product (around 5 years).
Both these models were released in 2014.
I found the Nuvi 65 LMT (6" at 800x480) for $158.85 (use coupon RYDAMX14 for free shipping): https://www.ryda.com.au/ProductDetails.asp?ProductCode=NUVI6…
DSE is selling the same model for $229, JB-Hifi for $229, TGG for $218 and HN for $188 (on sale).
According to my findings, Ryda is a genuine Garmin Australia distributor.
The second model is the Nuvi 55 LM (5" at 480x272) for $118 on clearance: http://www.thegoodguys.com.au/garmin-nuvi-55lm-5-inches-gps-…
RRP (according to the Garmin website) are $229 and $169 respectively.
I hope it will help you, if you are in the market for a new GPS unit!
If you buy one please don't stick it in the middle of your windscreen under your rear vision mirror. Every time I see that I have an overwhelming desire to ram that car.
