I have been looking for a good GPS receiver and the Q818 particularly with the MKII chipset is always recommended. I have easily available to me the Q890 with the MKII chipset bluetooth GPS receiver.
From the specs it appears to be identicle to the highly recommended Q818X unit but it has an intergrated smaller battery.
Has anyone used it and how does it performance compared with the Q818X.
Is there anything to worry about ie a different antenna which may effect performance.
