    Mate, the model name means nothing. A 1390 could be named as 1234 by it's internal programming and it would still function as a 1390. Those other area units such as you mentioned are 1390s with a different model number, that's all. In some places, maybe they did have a mike fitted in the case but again it means nothing without the BT module. The thing which determines the BT function is what hardware is included to enable BT, and my US 1300s doesn't have the BT module or the mike. Have a look at this video, it's a US 1300:

    See when he finally opens it, no mike lead to the PCB same as my US 1300:

    1300 open

    If you want to check, open your unit following that vid to have a look. If you do, be very careful when finally splitting the case so you don't pull the screen ribbon off the board accidentally.

    Thx Neil. Sorry for delay in posting - have been away a few days. Yes I realise what you are saying about model numbers. However I see in the video on battery replacement that there are 2 cut-out spaces in pcb near mic slit so I guess that is to accommodate the mic body (and maybe a BT mini module). Maybe the pcb for BT models has an extra chip soldered onto the pcb (and therefore not pluggable into a empty socket). Would like to resolve this once and for all - ANYONE know anything about the physical pcb differences between non-BT Nuvi 1300 and the other 13XX with BT?

    Just hoping ....
