Hello all, I have a 2005 limited runner, as of now I have the OEM nav head unit but I would like to upgrade it to possibly a newer Toyota head unit with Bluetooth and maybe some other nice options. The only must have, is it has to still keep the maintenance reminder menu as the stock 4th gen head unit I have now. I really rely on this to keep my oil changes and other maintenance items on track. That's the only thing holding me back from buying an after market one. Wondering if anyone has any idea of which radio head unit would have this?
