3598LMT-D is same unit hardware as 3597LMT, not 3590LMT as linked in the GPStracklog review above. The difference between 3597/8 is only in the packaged traffic receiver, the EU 3597 has GTM36 FM only and the 3598 has GTM70 DAB/FM [plus 30 quid difference in price of course]. Being the sole representatives of the Garmin 'Prestige' range, i doubt Garmin would be pleased with Amazon describing 3597/8 as 'end of life' even though it's now a couple of years since it's initial release. Maybe Amazon knows something and we'll see some replacement Prestige model[s] soon.

I have a US purchased 3597LMTHD, which is same hardware as 3598LMT-D but packaged with a GTM60 HD Radio/FM receiver. I'm very pleased with the 3597 and choose to use it in my daily drive car in spite of it having an in-dash Denso nav unit because that lacks both traffic and safety camera alerts.
