i didnt know there were so many different types of nuvi's with various features. thought "BT capability" would mean all of them would have obd2 gauage metering if i had a OBD2 BT transmitter... but no.

so i decided to keep my 1490 in my Z and look at getting a bt module attachment for my pioneer HU in my G, but then read poor reviews on the pioneer bt module auto-pairing to motorola phones... they work well with iphones and some android phones, but not all.

so got the visor clip type bt speakerphone with auto on/off. the roadster2 is the only one that i know of that has auto on/off with car door open/close.

b&h has the best price.
