Failed to update the satnav map. Apparently the USB stick is faulty.
Don't waste your time.
Tandy supply the Nav for Jaguar using stock from 1972.
Mine works very well, thank you, apart from its 7yr old map missing a bit too much (and the shitty early X351 touchscreens being a bit unresponsive).
What would work better?
If it knew where it was going.
If it was aware of junctions that have been in place for forty years.
If it told me to turn left or right rather than have me guess.
If it used proper road names like A14 or B4535 rather then calling it Derek Johnson Way or similar crap I've never heard of.
If it didn't turn mute when I need information most.
Not suffered these problems, bar taking me through town instead of the 5yr old bypass every time I go to mums. Although, invariably, I have the voice turned off, and rely on the pop-ups on the dash next to the speedo.
Is yours the In Touch one? Mine is the older hdd gen 2.1 variant.
My biggest complaint is, unlike Omega/Signum/Vectra/Zafira, you can't enter a destination via the steering wheel, though the Jaguar Voice is incredibly accurate for me, even at very high speed.
