Replacing old unit

[autocolor]

Hi All new to this forum so hope I an in the right section
I have been running an old Pumpkin unit Model S07 in my 2008 Corvette since December 2014, its been OK but is now getting somewhat tired and with only 1GB struggles to download map updates constantly telling me there is no space, I run Sygic sat nav but the latest version of that is not compatible with this old unit.
So to cut to the chase what would be the best unit to update to that has the same basic spec as the S07, sat nav SD / std SD / 2 USB connectors / 1 apple connector etc.
The S07 is a 7" double din with just std FM radio, do the newer units also run DAB and does that come without the need for extra adaptors?
My main concern is fitting, will the connections all be the same or will I need yet another specific Harness?

Thanks for any advice you can offer

Mike

Unfortunately it seems this forum has not improved at all since I first purchased my unit in 2016, either very slow or no response to posts, and despite people giving details of their problems the reply is always send your order details.
Have emailed customer services who took over 24 hours to respond once with no information, still waiting for a second response.
Decided to go with a proper company with reliable customer service and technical team.
