Sorry to revive an old thread, but I couldn't find much on the topic.
Hi new member here, my wife just bought a 2006 (3rd gen) RX350. Has no USB or aux input - currently using one of those tape --> 3.5mm adaptors.
I'm looking for a complete solution for USB / BT / Aux input which will display on the sat nav screen and utilise steering buttons. But also don't want to interfere with the in-built BT phone functionality I'm considering a Pure Highway 300di as that is a DAB and has aux / USB input, but no steering controls or BT. But it's also well-priced at around $200 and the digital radio would be good.
Other possibility is Grom-type unit which should allow all functionality, but no digital radio.
There are some Dension units on Ebay from Germany which appear to do everything, but unsure about reliability or build quality: http://www.ebay.com.au/itm/USB-iPod-iPhone-Bluetooth-for-Lexus-Rx300-Rx330-Rx400h-Rx350-Sc430-/221850640252?hash=item33a7541f7c
It seems the Vais is now discontinued? I can't find much on the SL3i at least, and we don't have any Apple products (all Android) so this probably wouldn't suit anyway.
Any info would be appreciated. Cheers
