Unfortunately I got a slightly different product delivered, but satisfy the specifications of RBT1000.
The GPS receiver did not include meaningful under four (4!) Verscheidenen Android devices.
The compound was displayed but the desired effect failed to materialize; the positional accuracy was unfortunately very inaccurate +/- 10 meters ... which does not correspond in my opinion to the prior art.
In addition, the recipient of various card applications (eg locus per) was not detected or the connection broke off repeatedly.
Have returned logical device. The return went smoothly.
