SatNav

Do the later HDD navs have full postcode capability?

Can you upgrade the discs on the earlier models to take full postcode input.

Apologies if this has been covered, but I couldn't find out with a search

[F.A.]

I’ve never had an ISF but I had a ‘ 07 IS250 with the DVD based sat nav and a ‘11  IS250 with the HDD based nav. To my knowledge these systems were the same on the IS250 as the ISF.  The HDD system could take full post code input,  but, as you are aware,  the DVD system couldn’t and I wasn’t able to upgrade to this feature  with a later DVD disc.

The HDD sat nav in my 2011 ISF had full post codes.  

Unfortunately can’t help re whether you can update earlier sat nav though.

Don't think it can be updated but even then it would be like having a top of the range VHS player.

I have updated my 2009 ISF with the latest disk but it only updates the maps and not the postcode search / operating functionality. Its the only thing that annoys me about all Lexus of a certain. Its the same in my IS300. Love both cars but just hate both crappy sat navs. I use google on the phone instead.

If u open my glove box there will be a sat nav within it!......absolutely awful units and phone transfers don’t work either!.....did on my IS250 but that had an after market (Lexus) Bluetooth unit! The one serious flaw that I think the ISF has 😔

Can you swap the units over, I mean replace 08 unit with one from a 10 plate with HDD. They look like they would be a straight swap, may have to get it coded to the car?

Wouldn't bother tbh. I use Google maps on my phone and I have the HDD version. 

If you do have to use it, it'll get you there...eventually. But Google maps/waze is always receiving live data, and will reroute if needed. 

Far superior. 

There are also options to swap the head unit out for an Android unit, which again would be far superior. Someone on here has done it to their isf, and it looks great.

the fit on the Androids is questionable and from what I understand they are far from plug and play
