So it looks like me posting my Columbus out of the country (Ireland) is going to cost an arm and a leg to get the NAND reset. (€40+)

this really leaves me three choices,

1. pay the exorbitant postage plus what ever the repairer charges for their work and of course the return postage. (Most of the way there to paying for a brand new unit)

2. buy a 2nd hand replacement from ebay etc (not keen on this as you dont know if it has issues, or whether its even up to date)

3. buy a brand new android unit that would give me the additional features and up to date maps that I would like.

I am sure there many that have replaced their units with android devices so looking for recommendations.

Must haves

1. independent SATNAV (not driven by mobile phone)

2. Plenty of storage

3. as much compatibility as possible with the cars wiring and electronics (simple install no loss of existing functions), no hacks to cars existing wiring loom or electronics. Onboard diagnostics display would be a HUGE bonus.

I don't have a apple phone (and never will) so not looking for anything to do with IOS or carplay

I recommend MIB STD2 PQ unit.
