Just bought a Garmin Nuvi 1390T from Officeworks this afternoon for $254
The link goes to a 1390 model but from the looks of things Officeworks are selling the 1390T as the 1390 code in there system
It even came with a Garmin Carrying Case when the guy took it out from behind - https://buy.garmin.com/shop/shop.do?pID=35159
I know Myer also has just the 1390T for $254 saving $75 (if I recall correctly)
JB Hi Fi has it for ~$308 (I think) and they wouldn't price beat Myers $254 they could only match it
There website on the other hand says $287 - http://www.jbhifi.com.au/car-sound-gps-navigation/gps/garmin…
DSE has it for $324 - http://www.dse.com.au/cgi-bin/dse.storefront/4c1dd0d4037636b…
The 1390T is from the looks of things just a 1390 with the GTM-25 (Traffic Receiver 12v cable instead of a standard 12v cable)
Not a bad price with the SUNA Traffic.
