Hi everyone,

I just bought a IS250 2008 and I'm really dissapointed by the old headunit. I would like to upgrade the navigation screen to connect my Android or go on Google Maps.
I found some magic boxes to plug in the head unit, but I would like your opinion if somebody try them.
I found the Vais IVIC-5D, but it seems to be discontinued. Does somebody know where to find it?
There's also GROM USB that make a 500$ box.
Finally, I found ISimple who make a 150$, but it seems to be cheaper.

Do you guys know these products?

Thanks in advance,

Bert K
