Thanks for the above trick.
I can now confirm the new orange ROM 126.96.36.199 works with SPV C500 + Holux GR-231.
Those are the steps I followed.
1. don't rename BT to Tomtom Wireless GPS, paired BT to C500
2. install the anygpstweak.cab (by transfering it to \Storage\windows\Start Menu\Programs and run from C500) ---- thanks for TrickUK
3. Go to bluetooth setup>Menu>COMport - uncheck "secure connection"
4. run tomtom and select other BT - Walo.... everything working now.
:twisted: :oops: :x
Can not get it to work.
I got the Dutch Rom
I did a hard reset
I paired my HOLUX GPSlim236 with the phone. So it is connected as "HOLUX GPSlim236".
Went to the home screen (bluetooth is on)
Run the the AnyGPSTweak program.
Went back to the bluetooth setup en then to menu item Com port. What I thought there should be an Outgoing Comport made by the above program and the I could just uncheck Secure connection but this was not true.
So I made an outgoing Comport (To the HOLUX GPSlim236) on Com6 unchecked Secure connection.
After that I shutdown bluetooth and the phone.
Restarted the phone and ran TomTom. Here I allready said that I had Other GPS!
Now TomTom says there is now GPS!!! The round thing is turning so some communication but TomTom does not see my GPS
Does anybody has a tip for me????
