Bluetooth internal differences TTG-> TTG300,500,700

[tyrwin]

Having bought the TT GO just before the arrival of the TTG 300, 500 and 700 (doh!) I was wondering if anyone has had a look inside the new models yet.

I saw some exploded pictures when the Pocket GPS staff did their initial review of TTG. Is the TTG 300 etc that different internally ?Reason for asking is - Bluetooth dongles are very cheap now (£10) and by wiring the innards (stripped of packing and USB connectors) even on a daughter board I thought might it be possible to add at least the handsfree capability to my "old" TTG? I amazed from this site how many mods are possible on the TTG.

Thanks
